HTML 5 is being described as the future of the Web but naturally, unless you understand what benefits it holds for your website or online business, you may not be sure if you really want to look into it.
A website is powered by a special coding language, called the markup language – Hyper Text Markup Language or HTML. A markup language, as the name suggests provides structure to the information on the page, indicating what block of text is the heading, what forms a paragraph, a hypertext link, a list and so on. The most commonly used markup languages today are HTML 4 and to some extent xHTML. Both these markup languages contain a set of elements, which when applied correctly to the information in your website documents will give them the correct semantics and more importantly have a better chance at being understood by a wide variety of user agents.
What do we mean by semantics? Semantics, for website documents, simply means giving meaning to a structure. While designing webpages, HTML elements should be used to give proper meaning to the content. For e.g. <title> is used to indicate the title of the document, (<h1>, <h2>, <h3>) are used to indicate various headings, <a> a hyperlink, <abbr> an abbreviation and so on. However, the problem for web standard experts so far has been the very limited set of elements available for HTML 4. This has made it difficult to semantically describe all the content of the pages effectively. HTML 5 provides a much larger set of markup elements that experts hope will help provide better semantics to a webpage.
At this stage, you might still not be convinced about how HTML 5 is going to benefit your website. Let us consider two examples to explain why HTML 5 is superior to the previous markup language.
- If you use HTML 5 to markup the content of your website, there may not be any visible changes in the external appearance of your website. Your visitors will only see the design of your website. However, they are going to use a wide variety of devices and methods to view your site. This may include technology that groups information for them based on the semantic indicators that you have provided on the webpages, a mobile browser that re-organizes content using the semantic information so that it can be viewed easily on the small screen or search engines that are able to index and rank your site better because of better semantics. In other words, you are bound to benefit from the use of HTML 5.
- Another major advantage of HTML 5 is its ease of use. Currently, media such as video cannot be handled by HTML 4 and a user has to download third-party plug-ins such as Adobe Flash or Microsoft Silverlight to play videos. On the other hand, if a site is using HTML 5 and a compatible browser is being used to view the site, no third-party plug-ins are necessary and the browser can display the video as naturally as it can images at present. Thus site designers can make websites as media-rich as they want by using video, audio and other interactive media.
HTML 5 can thus provide for a smoother, richer user experience across a range of devices, once it is fully supported by all major browsers.
