HTML vs HTML5 — What Is the Difference?

As you may know, HTML (Hypertext Markup Language) is the backbone of every web page on the internet. It is a markup language that describes the structure of web pages using tags and attributes.

Like everything else in the tech world, HTML has evolved immensely since its inception in the late 1980s. Those who are new to coding should familiarize themselves with its latest incarnation — HTML5. But having a thorough understanding of the language’s evolution can give both budding and veteran coders some perspective on the past, present, and future of web development.

In this article, we will discuss the differences between HTML and HTML5 and how they have impacted web development.

The basics of HTML

HTML code instructs web browsers how to render content. It explains the underlying structure of a web page. For decades, HTML has been considered a cornerstone technology of the World Wide Web along with Cascading Style Sheets, or CSS, and JavaScript. Standards for both HTML and CSS are maintained by The World Wide Web Consortium.

As its name implies, HTML isn’t technically a programming language; it’s a markup language used to organize data from the Internet. HTML documents are composed of HTML elements represented by tags, which are written inside angle brackets, to categorize content. An example of the HTML structure to display a simple «Hello World» message would look like this:

HTML documents delivered from web servers let the browser know how to present text in addition to embedding links, images and interactive forms.

The history of HTML

Rather than rendering older versions obsolete, each new version of HTML has focused on making Internet technology more accessible to everyone. For example, in addition to introducing new options for creating templates, HTML4 improved accommodations for visually impaired Internet users.

The last major overhaul of HTML during the late 1990s was a major collaborative effort by global experts to internationalize the language and make it easier for coders across the world to collaborate. As a part of this effort, the Universal Coded Character Set was adopted as the official HTML character set. This move allowed browsers to better represent the many characters and accentuations present in human languages and dialects.

As a result, we now have better archive indexing for more accurate web searches in addition to top-quality typography. With the introduction of HTML4, web designers also gained more control over the speed and order of content rendering.

HTML vs HTML5: The evolution of web development

The Internet is a very different place than it was in 1999 when the last major update, HTML4.01, was implemented. Technologies exist today that we couldn’t have imagined before the turn of the century. Smartphones, tablets and other mobile devices have introduced new challenges to engineers and software developers. Increased globalization has made the standardization of Internet technology a top priority for everyone with a stake in the world economy. Internet usage worldwide continues to grow year after year and the technology used is projected to evolve at an increasingly faster rate.

Therefore, HTML5 was implemented to start addressing these issues to provide a smoother and more consistent experience for web users and developers.

HTML5 is the result of a collaboration between the World Wide Web Consortium, or W3C, and the Web Hypertext Application Technology Working Group, or WHATWG. The organizations teamed up in 2006 to reduce reliance on plugins, improve error handling and replace scripting with more markups. Consequently, HTML5 has greatly simplified the process of creating web applications.

Thanks to HTML5, web pages can now store data locally on the user’s browser, which eliminates the need for HTTP cookies. As a result, content can be delivered faster and more securely. HTML5 has also made it easier to ensure consistency across all browsers. Since browsers have traditionally relied upon different plugins to play multimedia files, native support of video and audio allows developers to avoid compatibility issues. New attributes also allow for video controls including play, pause, and volume options.

Gradual implementation

Because HTML4 was the standard for about 15 years, many coders still use it, and all browsers will continue supporting it for a very long time. Likewise, older browsers can «overlook» new HTML5 code while rendering content. Virtually all modern browsers including Chrome, Firefox, Mozilla, Opera and Safari now all support HTML5 specifications fairly well. Because HTML5 is constantly evolving, browsers are incrementally introducing support for new features. Fortunately, all of the major browsers have been consistently adding support for features as they are released.

You can use HTML5test to run a test with your current browser to see what it scores in terms of HTML5 support.

There is no need for most developers to overhaul their old webpages; however, anyone with a future in website creation should learn to take advantage of the many benefits of HTML5 vs HTML.

HTML vs HTML5: What is new?

If HTML was fine for over a decade, why was it updated in 2014? The most significant difference between older versions of HTML vs HTML5 is the integration of video and audio into the language’s specifications. The image below provides a quick overview of HTML5’s major features broken down by category.

Semantic tags

One of the most significant changes in HTML5 is the introduction of semantic tags. Semantic tags are designed to describe the content they contain, making it easier for search engines to understand the content of a web page. These tags include header, nav, section, article, aside, and footer.

For example, the header tag should contain the header section of a web page, while the footer tag should contain the footer section of a web page. By using semantic tags, developers can create more accessible and search engine-friendly web pages.

Audio and video support

HTML5 has introduced native support for audio and video, which eliminates the need for third-party plugins like Flash. This means that web developers can now embed video and audio files directly into web pages using video and audio tags.

The video tag allows developers to specify the source of the video, the size of the video, and other properties. The audio tag works in the same way, allowing developers to specify the source of the audio file, the controls, and other properties.

Canvas

HTML5 has introduced the canvas element, which allows developers to create dynamic graphics and animations directly on a web page. The canvas element provides a powerful API for drawing shapes, lines, and text and allows developers to create interactive animations.

With the canvas element, developers can create games, data visualizations, and other dynamic content that would have previously required plugins or separate applications.

Local storage

HTML5 has introduced the ability to store data locally on the user’s device. This means that developers can now create web applications that work offline and still retain the user’s data when they reconnect to the internet.

The local storage API allows developers to store and retrieve data from the user’s browser, making it possible to create web applications that function similarly to native applications.

Mobile compatibility

HTML5 has been designed with mobile devices in mind, which means that web pages created with HTML5 are more compatible with mobile devices. HTML5 provides better support for touchscreens, accelerometers, and other mobile-specific features.

This means that web developers can create responsive web pages that adapt to different screen sizes and resolutions. Additionally, HTML5 provides support for geolocation, which allows web applications to use the user’s location for location-based services.

Improved accessibility

HTML5 has introduced many new features and attributes that make web pages more accessible to people with disabilities. These include the alt attribute for images, the aria-* attributes for describing the purpose of elements, and the role attribute for specifying the type of element.

The aria-* attributes are particularly useful for describing the purpose of elements to screen readers, which can make web pages more accessible to people with visual impairments.

Better performance

HTML5 has been designed with performance in mind, which means that web pages created with HTML5 are faster and more efficient than those created with previous versions of HTML. The improved performance is achieved through a combination of new features, such as the canvas element and local storage, and improvements to existing features, such as the ability to load scripts asynchronously.

Additionally, HTML5 provides better support for caching and offline storage, which can significantly improve the performance of web applications.

What are the advantages of HTML5 vs HTML for web users?

Now that we’ve covered the technical side, what are the advantages of HTML5 for regular web surfers? Here are some benefits you may or may not have noticed since developers started using HTML5:

• Some data can be stored on the user’s device, which means apps can continue working properly without an Internet connection.
• Web pages can display more fonts with a wider array of colors, shadows, and other effects.
• Objects on the page can move in response to the user’s cursor movements.
• Interactive media, such as games, can run in web browsers without the need for extra software or plugins. Audio and video playback also no longer require additional plugins.
• Browsers can display interactive 3D graphics using the computer’s own graphics processor.

By limiting the need for external plugins, HTML5 allows for faster delivery of more dynamic content.

What are the advantages of HTML5 vs HTML for web developers?

A major focus of HTML5 was to give developers more flexibility, which in turn would lead to more engaging user experiences. HTML5 was conceived with several goals in mind:

1. Consistent error handling

All browsers have parsers for handling syntactically or structurally improper HTML code, or «tag soup.» However, until recently, there was no written standard for this process.

Therefore, new browser vendors had to test malformed HTML documents in other browsers so

that they could create an error handling process through reverse-engineering.

Malformed HTML is an unavoidable fact of life; according to Rebuildingtheweb, about 90 percent of webpages are estimated to contain some improper code, so error handling is vital for properly displaying websites. Consequently, codified error handling can save browser developers a lot of time and money. The benefits of a clearly defined parsing algorithm cannot be understated.

2. Support for more web application features

Another goal of HTML5 was to enable browsers to work as application platforms. As websites became more complex, developers had to find ways to «work around» browser extensions and other server side technologies. HTML5 gives developers more control over the performance of their websites. Many of the Flash and JS-based hacks commonly used in HTML4 are now elements inherent to the language. These changes also allow for a faster and smoother user experience.

3. Enhanced element semantics

The semantic roles of some existing elements have been improved to make the code more insinuative. New elements like section, header, article and nav can replace most div elements, which makes scanning for mistakes a less painful process.

4. Maximized mobile support

Mobile devices are notorious for giving web developers headaches. Their rapid proliferation over the last decade has made the need for better HTML standards more urgent. Users expect to access web applications from anywhere, anytime on any device, so developers have been forced to meet the demands of the market. Fortunately, HTML5 makes mobile support easier by catering to «low-fueled» devices like smartphones and tablets.

5. Easier development

HTML5 includes several new features that make web development easier and more efficient. For example, the introduction of semantic tags makes it easier for search engines to understand the content of web pages, while the canvas element allows developers to create dynamic graphics and animations directly in web pages.

6. Enhanced performance

HTML5 allows developers to create more optimized web pages, resulting in faster load times and improved performance for users. This is achieved through features like asynchronous loading of scripts and stylesheets, which means that these resources do not block the rendering of the page.

Other notable improvements

Now that a few years have passed since the launch of HTML5, several major companies have converted their websites, and many developers are sharing their opinions on HTML vs HTML5. Features that have been commonly cited as favorites include:

1. Support for custom data attributes

Adding custom attributes in a tag was risky before HTML5. With HTML4, custom attributes wouldn’t prevent pages from rendering completely, but they could result in an invalid document, which would cause browsers to render in quirks mode. The data-* attribute has taken care of this problem.

The data-* attribute has multiple uses, but its primary purpose it to store additional information about elements. Data is stored as a simple string. The inclusion of custom data lets developers make more engaging web pages without relying on Ajax calls or server side lookups.

2. No more cookies thanks to local storage

Although its already been mentioned, support for local storage has been a real game changer. Before HTML5, cookies were the only reliable way to store state information. Of course, cookies hold a very limited amount of data, and some web users disable cookies by default. HTML5’s localStorage object provides developers a way to work around the stateless nature of the HTTP protocol.

Because it is part of the global window namespace, localStorage may be accessed from any point within scripts. Only string values may be held in local storage, but the JSON.stringify() and JSON.parse() methods make serialization a quick and easy process. Alternatively, sessionStorage allows data to be stored only until the visitor closes their browser.

3. Form field autofocus

The form field autofocus attribute lets developers designate which form field will have input focus once the page loads. Of course, only one form element per document may utilize the autofocus attribute, and the user can override it by selecting a different field. For example, by adding autofocus to the Last Name input element as shown in the screenshot below, we can see that upon loading the page the Last Name input box is automatically highlighted.

4. Script and link tags no longer require type attribute

Since it’s now implied that script and link tags refer to scripts and style sheets respectively, the need for the type attribute has been eliminated.

The future of HTML vs HTML5

HTML5 represents a significant upgrade over its predecessor, HTML, and has become the preferred choice for web development today. HTML5 brings many advantages for both web users and developers, including improved functionality, multimedia support, accessibility, faster page load times, easier development, enhanced performance, and mobile compatibility.

HTML5 has also opened up new possibilities for web development, allowing developers to create more immersive, interactive, and engaging web experiences. With the introduction of features like the canvas element, WebSockets, and the Web Audio API, developers now have the tools to create complex games, real-time communication apps, and other interactive applications directly in the browser.

Looking ahead, there are several other improvements that might be coming in HTML5. One area of focus is likely to be on further improving performance and optimization, with features like lazy loading of images and scripts and more efficient resource management.

Another area of interest is likely to be on improving accessibility and usability, with new features to help make web content more accessible to people with disabilities and more user-friendly for all users. Additionally, there may be new tools and frameworks developed to help streamline and simplify web development further.

HTML vs HTML5 : What is New in HTML5?

This comparison on HTML vs HTML5 is intended to provide a crisp knowledge about both the markup languages and guide you to find the suitable one if you are building your own web page or web application. This HTML vs HTML5 article will provide you with a complete insight into the language in the following sequence:

• History of HTML
• Introduction to HTML & HTML5
• Comparison between the Two
• New Elements in HTML5

History of HTML

The history of the hypertext markup language is a strange and interesting tale. The man behind HTML, Tim Berners-Lee was putting together his first elementary browsing and authoring systemfor the Web and created a quick little hypertext language that would serve his purposes.

But the problem lied in the simplicity of the language. HTML was text-based and anyone could use any editor or word processor to create or convert documents for the Web. The developers started implementing new features in their browsers and started releasing advanced versions of HTML.

Introduction to HTML & HTML5

HTML stands for Hyper Text Markup Language and it is the standard markup language for creating web pages and web applications. It is used to describe the structure of Web pages using markup.

HTML5 is the 5th version of HTML and is a core technology markup language of internet that is used for structuring and presenting the content for www.

Comparison between the Two

Now lets have a look at all the new elements that were added in HTML5 and the factors that make it better than HTML.

Let’s look at the factors we will be using for the comparison on HTML vs HTML5:

• Video & Audio
• Vector Graphics
• Storage
• Web Browser Support
• Ease of Use

Video & Audio

The first factor in HTML vs HTML5 is the introduction of audio and video in HTML5. There was no such concept of media in case of HTML. But it is one of the integral part of the 5th Version.

Vector Graphics

Vector graphics was used in HTML with the help of various technologies such as VML, Flash, Silverlight etc. But it is an integral part of HTML 5 such as canvas and svg. This was a new addition to the revised version.

Storage

The third factor of comparison is storage. In case of HTML, we can use the browser cache as the temporary storage whereas in case of HTML5, application cache, web SQL database and web storage is used.

Web Browser Support

Now for the first version of HTML, all the old web browsers run smoothly for creating web pages. For HTML5, the new browsers have started supporting its specifications. Some of the browsers include mozilla firefox, chrome, opera etc.

Ease of Use

While HTML5 does have risks like constant updates, it is generally easy to keep up with the changes and updates because of the simpler syntax as compared to other versions of HTML. For instance, you have a very simple declaration at the start of the page to set it as an HTML5 page, ie, the doctype declaration.

New Elements in HTML 5

The comparison on HTML vs HTML5 also includes new elements and tags that have been added to the latest version. HTML5 comes with a number of new elements and eliminates several others. Some of the tags were discarded in the new HTML version and the usage of tags were changed accordingly.

Let’s have a look at some of the important tags that were added in HTML5:

< Audio & Video >

The audio tag and the video tag are the two major additions to the HTML5. The audio tag and the video tag enables developers to embed music and audio on their website.The audio & video tags also have a number of attributes for additional controls.

There are a few other multimedia attributes and elements that come with HTML5, like the track element that provides text tracks for the video element.

< Canvas >

One of the key added elements in HTML5 is <canvas> which has hugely impacted the use of Adobe Flash in websites. The <canvas> element can be used to draw graphics with various shapes and colors via scripting, usually JavaScript. The element is simply a container for the graphics.

< Header > & < Footer >

Another big addition that HTML5 comes with are the new <header> and <footer> elements, indicating a new web anatomy. With these new tags, there is no longer a need to identify the two elements with a <div> tag.

The footer is placed at the bottom of the web page but it can also be placed at the end of a page section.

Given the fact that the web has changed into more just linked paged and documents, the <menu> tag is a welcome addition for greater web interactivity. It represents menu commands for simplicity in desktop and mobile applications.

Now with this, we come to an end of this comparison on HTML vs HTML5. I Hope you guys enjoyed this article and understood the difference between the two versions and how HTML5 is better and simpler in use. So, if you have read this, you might have a clear idea about which version of HTML you should opt for, while building your own web page.

Что такое HTML5 – Различия Между HTML и HTML5

Люди, плохо знакомые со сферой веб-дизайна, часто слышат слово «разметка» и задаются вопросом, что оно означает и как отличается от более широко известного термина «код». В основном язык разметки предназначен для обработки, определения и представления информации о тексте; теги стилей и текстовые аннотации записываются в файлах стилей, чтобы упростить работу с текстом для компьютера. Исторически сложилось, что термин «разметка» произошел от английского marking-up, а сам процесс от manuscript marking-up — процесса разметки рукописи перед отдачей ее в печать. Здесь речь пойдет о наиболее часто используемом языке разметки — HTML. Несколько лет назад для этого языка было выпущено обновление под названием HTML5. В этом руководстве мы расскажем, что такое HTML5 и поведаем о различиях между HTML и HTML5.

Что такое HTML?

HTML можно назвать основным языком Всемирной паутины. Большинство веб-страниц, размещенных в Интернете, написаны в какой-либо из вариаций HTML. С помощью него разработчики определяют то, как мультимедиа, текст или гиперссылки будут отображаться среди другого контента в браузере. Начиная от элементов, которые устанавливают связи с вашим документом (гипертекстом), до элементов которые делают эти документы интерактивными (например формы) — все это является составными частями HTML.

Стандарт HTML был разработан W3C или Консорциумом Всемирной Паутины в 1997 году. В HTML для определения структуры текста используются теги; теги и элементы выделяются с использованием символов < и >. Вот лишь некоторые из примеров для ранее упомянутых тегов — это заголовки, таблицы, абзацы и т. д. В свою очередь, браузеры отвечают за визуализацию содержимого страницы с помощью этих тегов. HTML не был единственным стандартом веб-разработки. В первые дни развития Интернета все теги контента и стили присутствовали на одном гигантском, громоздком (и довольно сложном) языке. Со временем W3C пришла к решению о необходимости разделения контента и стиля страницы; Это привело к созданию таблиц стилей или CSS. В настоящее время теги, которые используются для определения стиля текста (например FONT), нежелательны и почти не используются, на их место пришли таблицы стилей и только теги определения содержимого (например H1) по-прежнему составляют ядро ​​HTML.

С течением времени в HTML было много обновлений, и в настоящее время его новейшей версией является HTML5. HTML5, конечно прежде всего является языком разметки, но он приобрел множество функций в отличии от HTML и устранил некоторые из строгостей, присутствовавших в XHTML. Хотя HTML5 обновляется практически каждый день, однако новых выпущенных пронумерованных выпусков нет. Основным различием между HTML и HTML5 может стать то, что ни аудио, ни видео не являются составной частью HTML, тогда как они оба могут рассматриваться как неотъемлемые части HTML5.

Чтобы полностью ответить на вопрос что такое HTML, нужно затронуть и этапы его развития. Так как с течением времени он неоднократно изменялся.

Каковы основные различия между HTML и HTML5

Единственной постоянной вещью в области информационных технологий является то, что периодические обновления и изменения неизбежны. Ни один язык не может избежать обновлений или новых выпусков. HTML не является исключением. HTML5 был выпущен с целью улучшения работы Всемирной паутины как для разработчиков, так и для обычных пользователей. Как уже упоминалось, самым большим преимуществом, которое имеет HTML5 над своим ненумерованным предшественником, является то, что у него есть поддержка аудио и видео высокого уровня, которая не была частью спецификации в предыдущих HTML. Другие различия между HTML и HTML5:

• SVG, canvas и другая виртуальная векторная графика поддерживаются в HTML5, тогда как в HTML использование векторной графики стало возможным только при использовании его в сочетании с различными технологиями, такими как Flash, VML, Silver-light и т.д.
• HTML5 использует базы данных SQL и кеш приложений для временного хранения данных, тогда как в HTML для этого используется только кэш браузера.
• Еще одно отличие между HTML и HTML5, о котором стоит упомянуть: первый не позволяет запуск JavaScript в коде (вместо этого он работает в потоке интерфейса браузера), тогда как последний обеспечивает полную поддержку JavaScript для запуска в фоновом режиме.
• HTML5 не основан на SGML, и это позволяет ему иметь улучшенные правила синтаксического анализа, которые обеспечивают улучшенную совместимость.
• В HTML5, в тексте могут использоваться встроенные MathML и SVG, тогда как это невозможно в HTML.
• Некоторые из устаревших элементов были полностью удалены: isindex, noframes, acronym, applet, basefont, dir, font, frame, frameset, big, center, strike, tt.
• HTML5 поддерживает новые виды элементов управления, к примеру, dates and times, email, number, range, tel, url, search и т.д.
• В HTML появилось много новых элементов. Вот некоторые из самых важных: summary, time, aside, audio, command, data, datalist, details, embed, wbr, figcaption, figure, footer, header, article, hgroup, bdi, canvas, keygen, mark, meter, nav, output, progress, rp, rt, ruby, section, source, track, video.

Основные преимущества HTML5 для разработчиков

HTML5 предоставляет для разработчиков больше гибкости при разработке дизайна сайтов, и в этой сфере есть значительные улучшения, о которых стоит упомянуть:

1. Постоянная обработка ошибок:

Большинство браузеров поддерживают парсинг структурно или синтаксически неправильного HTML кода, но до недавнего времени для этого не было стандартного процесса. Это означает, что разработчикам новых браузеров необходимо производить тесты неверных HTML документов для создания более улучшенного процесса обработки ошибок. Постоянная обработка ошибок в HTML5 сыграла в этом процессе огромное значение.

Улучшенные алгоритмы парсинга, которые используются в HTML5 имеют неоценимые преимущества. Исследования показывают, что около 90% сайтов могут содержать некорректно написанный код, поэтому очень важно обрабатывать эти ошибки. Кроме того, присущая HTML5 обработка ошибок сохраняет разработчикам много денег и массу времени.

1. Улучшенная семантика для элементов:

Для упрощения и улучшения понимания кода были внесены улучшения в семантические роли различных существующих элементов. Section, article, nav и header — это новые элементы, которые заменили большинство из ныне устаревших div элементов. Это сделало процесс обработки ошибок менее сложным.

1. Расширенная поддержка функций веб-приложений:

Одной из главных целей HTML5 было создание возможности функционирования браузеров в качестве платформы для приложений. Веб-сайты в прошлом были намного менее сложными, но со временем громоздкость возрастала. HTML5 предоставляет разработчикам расширенный контроль над производительностью своих сайтов. Раньше разработчикам приходилось использовать обходные пути, поскольку многие серверные технологии и браузерные расширения отсутствовали. Теперь, при использовании HTML5 нет смысла использовать какие-либо JS или Flash расширения (как это было в HTML4), поскольку в HTML5 присутствуют элементы, которые обеспечивают все эти функции.

1. Создание мобильных сайтов стало проще:

Даже сегодня, создание мобильной версии сайта, это головная боль для разработчика. Увеличение популярности смартфонов в последние десятилетия создало необходимость в улучшении стандартов HTML. Сегодня пользователи хотят иметь доступ к веб-ресурсам в любое время и с помощью любого устройства, что накладывает определенные обязательства на разработчиков. HTML5 сделал в этом плане значительные улучшения, благодаря тому, что код HTML5 теперь лучше поддерживается маломощными электронными устройствами, такими как смартфоны и планшеты.

1. Элемент canvas:

Одной из самых обсуждаемых особенностей HTML5 является элемент <canvas>. Внедрение этого уникального тега произвело огромное влияние на Adobe Flash. Несмотря на то, что многие сайты до сих пор используют Flash, все больше людей склоняются к использованию HTML5, именно поэтому есть основание полагать, что Flash в ближайшем будущем полностью устареет.

Используя элемент canvas разработчики могут рисовать с помощью скриптов (например JavaScript) графические изображения с применением различных цветов. Стоит упомянуть, что canvas это обычный графический контейнер и для показа изображения необходимо выполнение скрипта. Вот пример использования JavaScript в сочетании с canvas:

1. Элемент menu:

Недавно добавленные элементы <menu> и <menuitem> являются составными частями интерактивных элементов, однако, они не очень популярны в сообществе разработчиков. Несмотря на это, эти два элемента могут быть использованы для обеспечения более лучшей интерактивности на странице.

Тег <menu> используется для простоты предоставления команд меню на мобильных приложениях и приложениях рабочего стола. Здесь показано возможное применение тега <menu>:

1. Настраиваемые атрибуты данных:

Добавление пользовательских атрибутов было возможно и до появления HTML5, но оно было связано с определенным риском, к примеру, в HTML4 пользовательские атрибуты могли приводить к остановке рендера страницы или что еще хуже, могли стать причиной неправильной работы документа. Атрибут data-* в HTML5 поставил точку в решении этой часто встречающейся проблемы. Этот атрибут имеет несколько предназначений, но основной целью его введения было хранение дополнительной информации о разных элементах. Теперь, благодаря этому атрибуту могут быть включены пользовательские данные, что дает разработчикам больше возможностей сделать привлекательные и эффективные страницы, без лишних запросов на сервер или вызовов Ajax.

1. (Возможное) прощание с Cookies:

Поддержка локального хранилища стала важным дополнением к HTML5. До появления HTML5, если разработчики хотели хранить что-либо на стороне пользователя, им приходилось использовать файлы cookie. Однако файлы cookie могут содержать лишь небольшой объем данных (не говоря уже о том, что все их ненавидят), это прибавило добавлению объекта localStorage в HTML5 еще больше преимуществ. Объект localStorage является частью глобального пространства имен и при использовании скриптов может быть доступен из любого места.

Шпаргалка HTML5

Если вы еще не знаете что такое HTML5 и с чем его едят, шпаргалка может быть отличным подспорьем при его изучении. Используйте приведенную ниже таблицу стилей HTML, для более продуктивного начала работы с HTML. Эта шпаргалка показывает наиболее часто используемые теги HTML.

Преимущества HTML5 для обычного пользователя

HTML5 привел к сдвигу устоявшейся модели программирования как для разработчиков, так и для обычных пользователей. Приведем примеры нескольких преимуществ для обычных пользователей:

1. Мобильные браузеры теперь работают более стабильно, чем стандартные приложения. До появления HTML5 ситуация была иная.
2. Сегодня ставка на адаптивные сайты (дружелюбные к мобильным устройствам) очень высока, так как почти 30 процентов пользователей мобильных устройств не хотят загружать специальные приложения. Это стало еще одним преимуществом HTML5, к примеру, если пользователь хочет использовать услуги компании, но не хочет загружать специальное приложение, он может просто зайти на сайт компании, чтобы сделать это.
3. Искоренение необходимости использования Adobe Flash позволяет разработчикам обеспечить более эстетичный пользовательский интерфейс. Использование JavaScript и MPEG4 в сочетании с HTML5 сделало жизнь пользователей намного лучше.
4. Возможность поддержки собственных аудио и видео элементов означает, что пользователям не придется загружать дополнительные плагины для просмотра мультимедиа на вашем сайте. Поддержка мультимедиа, предоставляемая HTML5, является одной из самых значимых причин, по которой он используется намного чаще чем HTML.

Заключение

Вряд ли новая версия любого языка может быть хуже предшественника и HTML5 не является исключением. С каждым годом разработчики узнают новые способы использования HTML5. Кроме того, ожидается, что в ближайшее время изменение затронет и социальные сети.

Несмотря на то, что волна изменений уже настигла многих разработчиков по всему миру, ожидается, что в ближайшие годы HTML5 еще более расширит свое влияние. Очень важно адаптироваться и узнать что такое HTML5 сейчас, чтобы максимально использовать возможности современных браузеров.

What Is the Difference Between HTML vs HTML5

HyperText Markup Language (HTML) is the most widely used markup language for creating web pages and applications. It comprises predefined elements and tags for labeling content pieces and describing the structure of pages.

We’ll go over the difference between HTML and HTML5 as well as the advantages of HTML5 for developers and end-users. In addition, we will answer the most frequently asked questions about HTML5 and provide an HTML5 cheat sheet to make the learning process easier.

Let’s get started.

What Is HTML?

HTML is the primary language of the World Wide Web (WWW). Developers use it to design web page elements, such as text, hyperlinks, and multimedia files.

HTML 5.2, upgraded in 2017, is the latest version of HTML. Check out the graphic below for more historical HTML milestones.

HTML works by using various tags, including those for headings, tables, and paragraphs, to define the text structures. Each tag is defined using the <A> and </A> formula. They are called an “opening” and “closing” tag, respectively.

For example, we might use <i>type your text here</i> to change the text style to italic. The browser will render the content via these tags, then display it on the screen.

Note that this language works only statically, so one cannot create a dynamic or interactive web page feature using HTML. It only modifies the static elements of a web page, such as the content header, footer, and image position.

To build an interactive website, you need to combine HTML with at least two front-end languages: Cascading Style Sheet (CSS) and JavaScript.

What is HTML5?

HTML5 is the latest version of HyperText Markup Language, which supports multimedia, tags and elements, improved document markups and new APIs.

HTML vs HTML5 – Comparison

Both HTML and HTML5 are hypertext markup languages, primarily used to develop web pages or applications. HTML5 is the latest version of HTML and supports new markup language functionalities such as multimedia, new tags and elements as well as new APIs. HTML5 also supports audio and video.

In addition to the features in the table above, HTML5 has seen the following changes:

• Some removed elements, like isindex, noframes, acronym, applet, basefont, dir, font, frame, frameset, big, center, strike, and tt.
• New form controls, including dates and times, email, number, range, tel, url, search, color, and datalist.
• Numerous new elements, including video, nav, aside, progress, canvas, section, meter, and time.
• New APIs with various functionalities such as drag-and-drop support, browser history manipulation, and reading and locking screen orientation state.
• New attributes including async, manifest, sandbox, srcdoc, and reversed.
• New global attributes, such as hidden, role, spellcheck, and translate.

Key Advantages Provided by HTML5 for Developers

HTML5 was created to improve the WWW experience and give web developers more flexibility when designing websites. In this part of the article, we’ll go over the significant improvements introduced by the new version.

Persistent Error Handling

Most major browsers have the support to parse structurally or syntactically incorrect HTML code. However, until a few years ago, there was no standardized process to handle this.

This means that browser developers had to perform malformed HTML document tests in different browsers to create improved error handling processes through reverse engineering.

The consistent error handling in HTML5 has made a massive difference in this regard, with the improved parsing algorithms used in HTML5 saving a large amount of both money and time.

Improved Semantics for Elements

Improvements have been made to the semantic roles of various existing elements in HTML to enhance code insinuation.

Section, article, nav, and header are the new elements replacing some obsolete div elements. Since the elements are more straightforward, the process of mistake-scanning becomes less complicated.

Enhanced Support for Web Application Features

One of the primary goals of HTML5 is to allow web browsers to function as application platforms. Thus, it provides developers with enhanced control of their websites’ performance.

In the past, developers had to use workarounds because many server-side technologies and browser extensions were not present.

Currently, there is no need to employ any JavaScript-based or Flash workaround as previously done in HTML4 because there are elements in HTML5 providing all the functionalities.

Mobile Web Made Easier

The smartphone-owning demographic has constantly been growing over the past decade, facilitating the need to improve HTML standards.

End-users want to be able to access web resources at any time via any mobile device. In other words, a mobile-friendly website is a requirement.

Luckily, HTML5 is more mobile-friendly compared to its previous versions as it caters to mobile devices like tablets and smartphones.

The Canvas Element

One of the most exciting features of HTML5 is the <canvas> element for drawing various graphics components, such as boxes, circles, text, and images.

However, it is worth mentioning that the <canvas> element is merely a graphic container. Thus, to define the graphics, a script has to be executed. Here is an example where JavaScript is used in conjunction with the element:

The Menu Element

The newly added <menu> and <menuitem> elements are components of the interactive element specifications.

These two items can be used in web development to ensure enhanced web interactivity. The <menu> tag represents menu commands in mobile and desktop applications for simplicity purposes. One possible usage of the menu tag is:

Customizable Data Attributes

While it is possible to add custom attributes to the older versions of HTML, it’s risky. Custom attributes can sometimes stop a page from rendering completely in HTML4 and cause incorrect or invalid documents.

Fortunately, the data-* attribute in HTML5 has brought an end to this problem.

This attribute’s primary objective is to store extra information about different elements. There are also other uses for this attribute, such as styling CSS elements or accessing an element’s data attribute via jQuery.

Custom data can now be included, giving developers the chance to make engaging and efficient pages without introducing complicated server-side lookups or Ajax calls.

Web Storage to Replace Cookies

HTML5 uses web storage or local storage to replace cookies. In the older HTML version, if developers wanted to store anything, they had to use cookies that hold a small amount of data – only around 4 KB.

However, cookies have several disadvantages – they can expire, restrict the use of complex data as they only allow string variables, and slow down performance by carrying additional scripts to the server.

By comparison, the local storage allows data to be stored permanently on the client’s computer unless the user erases it. It also features bigger data storage – at least 5 MB – and doesn’t burden the server with any requests.

HTML5 Advantages for End-Users

HTML5 presents a paradigm shift not only for developers but also end-users. Some of the advantages it provides for the end-users are:

• Reduces mobile browser crash rates.
• Supports native audio and video elements without any additional plugin.
• Offers geolocation of the user browsing any site or using applications based on an HTML5-compatible browser.
• Provides offline application caching so that pages or web applications are available even when users are not connected to a network.
• Enhanced web forms with improved text inputs, search boxes, and different fields for various purposes.

How Secure is HTML?

HTML5 is the most secure version of HTML. However, apps and sites built using HTML5 are still vulnerable to security attacks.

Common security threats typically come in the form of malicious code, which can be injected through various means such as developer error, music files, images, QR code, SSID fields, or the middleware framework.

Unfortunately, there is no one cure-all solution for building a secure website or web application using HTML5. The security of the site or application depends on how careful and thorough the web developer is in creating it.

In addition, one needs to understand the vulnerabilities of the platform used to build their website. For example, WordPress users must understand the content management system’s security vulnerabilities to secure their WordPress websites properly.

Here are some tips and tricks for improving website security:

• Keep software and plugins up-to-date. Software and plugin updates contain performance and security improvements, including bug fixes and protection against the latest online threats.
• Get rid of unnecessary plugins and files. Unnecessary and outdated plugins and files can serve to access the website and deploy security threats.
• Use HTTPS and SSL. HTTPS and SSL provide a higher level of security for a website. HTTPS encrypts HTTP requests and responses, while SSL creates a secure connection between website and browser to ensure the safety of private information.
• Create a robust password policy. Create a password policy requiring website users to come up with strong passwords which consist of a mix of letters, numbers, and special characters.
• Choose a secure web host. Find a trustworthy hosting provider offering 24/7 support and various features, such as website backup services, free TLS encryption, and a high uptime rate.
• Back up the website frequently. Performing frequent website backups prevents the loss of important information in the event of a security breach, as one can simply restore the website from a database backup.
• Scan the website for malware regularly. Various types of malware may enter a website through plugins or other files. Perform regular malware scans to rid the website of these security threats.
• Limit login attempts. Limit the number of login attempts to prevent hackers from trying numerous password combinations.
• Manage user access. Be strict in controlling user access and permissions, ensuring only authorized people can access sensitive files and information. This is especially important for websites with multiple users.
• Install Web Application Firewall (WAF). A WAF filters, monitors, and blocks malicious HTTP traffic traveling to the application. It can enable the URL lockdown feature, preventing unauthorized IP addresses from accessing a website’s login page.

Can I Learn HTML5 by Knowing HTML?

Learning HTML5 is practically the same as learning HTML, as HTML5 is just the new version of HTML. After mastering one version, writing code using another version of HTML should not be difficult.

These days, almost anyone can learn HTML on their own, which is made even easier through websites for learning to code for free.

HTML5 Cheat Sheet

Cheat sheets can help you in your journey to learn a new language. Below, we’ve provided a downloadable sheet containing the most commonly used HTML tags and new tags for HTML5.

Should I Switch to HTML5?

It may be good practice to switch to HTML5. One of the main reasons being that HTML5 has already replaced Flash for providing multimedia content on various platforms.

Lots of major industry names have migrated from Flash to HTML5. Examples include Apple, Youtube, and Google Chrome.

Here are more reasons to switch from Adobe Flash to HTML5:

• Adobe Flash is proprietary software. People using the software will be subject to restrictions or licensing conditions. HTML5, on the other hand, is open-source and developed openly by an international panel.
• Security and performance concerns. Experts have pointed out that Flash is unsafe and unstable. It has become a gateway for various malware attacks, and the way Flash content is processed also impairs load time.
• Battery-draining. Viewing Flash content on mobile devices tends to drain battery power.
• Flash is not suitable for touch devices. Flash technology is primarily designed for desktop devices, not touch devices. For example, many Flash applications rely on the hovering mouse motion, which is impossible on touchscreens.
• Adobe has stopped supporting Flash Player. Adobe announced it would stop supporting Flash Player from Dec. 31, 2020. It recognizes that open standards such as HTML5 have become better alternatives and are already used by major browser vendors.

To help you decide whether to switch to HTML5, here are some pros and cons of using HTML5.

Pros

• Free. No need to pay royalty or licensing fees for using it.
• Cross-platform. Available on any device – computers, laptops, smartphones – as long as the browser supports HTML5.
• Native audio and video support. HTML5 provides audio and video support without installing extra software or applications.
• May boost SEO. HTML5’s cross-platform nature and the new semantic HTML tags it introduced may boost a website’s SEO performance. In addition, Google has stopped indexing content in Flash sites or Flash content on pages.
• Reliable storage options. HTML5 allows the temporary storage of user data in an SQL database, eliminating the need for cookies.

Cons

• Different video formats. There is no definitive standard video format for HTML5. Examples of formats used include H.264, WebM, and Ogg. Different browsers support different video formats. For example, Firefox supports WebM and Ogg, but not H.264.
• Doesn’t support legacy browsers. Users using old browsers may not be able to access HTML5 websites properly. Some newly added features on HTML5 are only compatible with modern browsers.
• Inconsistent delivery. Despite its cross-platform nature, HTML5 content may be rendered differently depending on the kind of browser and device used.
• Media licensing issues. Some video codecs contain patented technology, which means that certain uses of these video formats are subject to royalty fees to the patent owners. For example, H.264, ACC, and MPEG-4 codecs fall under this category.
• Not ideal for game development. JavaScript is HTML5’s only scripting language. While ideal for numerous applications, it may be lacking for game development purposes, especially when dealing with custom namespaces, inheritance, or member access.

If you want to switch from Flash to HTML5, here is a brief step-by-step guide to follow:

1. Prepare for the transition. This may include auditing assets and deciding what to add or change, creating a cross-reference list to follow during conversion, and determining the conversion timeline, guides, and rules.
2. Check the source files. Find and document source files, making sure nothing is missing.
3. Collect media and content. Extract all media and content from the Flash website to be reused or converted for the HTML5 site.
4. Use the appropriate conversion tool. There are many tools for Flash to HTML5 conversion. Examples include Adobe Animate, OpenFL, and Google Web Designer. More will be explained later.
5. Test the new website. Once the conversion is complete, test the HTML5 website across different devices and browsers.

The kinds of Flash to HTML5 conversion tools to use depend on the files you have.

If you have the source .fla and .as3 files, we recommend using Google Web Designer or Adobe Animate. If you only have the .swf files, we recommend using tools such as Zoë from CreateJS or OpenFL.

Here are brief descriptions of each tool:

. Google’s free web editor for creating HTML5 web content using a combination of visual and code interface. It supports Windows, Mac, and Linux. . Adobe’s multimedia authoring and computer animation software. It supports HTML5 targets and provides a migration path to convert older Flash applications and games into HTML5. . An open-source application that is part of CreateJS, a suite of JavaScript libraries for creating interactive content. This tool converts .swf animations to sprite sheets. . A free and cross-platform software framework that implements the Flash API. Written in the Haxe programming language, the framework is often used for creating applications and games.
