What Is HTML5?
HTML5 is the newest hyper text markup language for websites from the World Wide Web Consortium (W3C). The first draft was made public in 2008, but not much happened until 2011. In 2011, HTML5 was released and people started writing about it and using it, but the support in different browsers was still poor. Today all major browsers (Chrome, Safari, Firefox, Opera, IE) offer HTML5 support, therefore the newest HTML technology can be used at its best today.

HTML5 is the successor of HTML 4.01, released for the first time in 1999. The internet has changed significantly since 1999 and it seemed like the creation of HTML5 was necessary. The new markup language was developed based on pre-set standards:
- New features should be based on HTML, CSS, DOM, and JavaScript.
- The need for external plugins (like Flash) needs to be reduced.
- Error handling should be easier than in previous versions.
- Scripting has to be replaced by more markup.
- HTML5 should be device-independent.
- The development process should be visible to the public.
What’s new?
HTML5 was created to make the coding process easier and more logical. You will see a bit later that many syntaxes are now deprecated and soon to be kicked out through the back door. The unique and impressive features HTML5 comes with are in the multimedia department. Many of the features it comes with have been created with the consideration that users should be able to run heavy content on low-powered devices. The syntactic features include the new <video>, <audio> and <canvas> elements, but also integration of vector graphics content (what we knew before as being the <object> tags). This means that multimedia and graphic content on the web will be handled and executed easier and faster, without the need of plugins or APIs.There are a bunchload of new syntaxes added, but below I will name and describe the most important. The rest of them can always be found in W3C’s HTML5 section.
- <article> – this tag defines an article, a user comment or a post, so an independent item of content
- <aside> – the aside tag marks content aside from the page content, which for example could be a lateral sidebar
- <header>, <footer> – you won’t need to manually name IDs for headers and footers, as now you have a pre-defined tag for them
- <nav> – the navigation can now be placed in the markup in between the nav tags, which will automatically make your lists act like navigation
- <section> – this is another important new syntax, as it can define any kind of sections in your document. It works pretty much like a div which separates different sections.
- <audio>, <video> – these two obviously mark sound or video content, which will now be easier to run by devices.
- <embed> – this new tag defines a container for interactive content (plugin) or external application
- <canvas> – the canvas tag is quite exciting, as it allows drawing graphics via scripting (mostly JavaScript, but some others can be employed as well)
Example of how HTML5 code looks like
Moreover, complex XHTML declarations many of us used before can now be replaced with <html lang=”en”> and long encoding declarations can simply be written in this way: <meta charset=”utf-8″>. Can it get simpler than that? It most definitely can’t.
The following tags from HTML 4.01 are now removed from HTML5, therefore browsers do not offer support for them anymore. This means that it is a good idea to go back to your HTML pages and check for them, as they might disrupt the design in the latest browsers.
- <acronym>
- <applet>
- <basefont>
- <big>
- <center>
- <dir>
- <font>
- <frame>
- <frameset>
- <noframes>
- <strike>
- <tt>
Things to know about HTML5
It is crucial to remember that HTML5 is built on the success of its previous version, HTML 4.01, which is undoubtedly the best version ever. In order to be better at using HTML5 you do not need to forget everything about the previous version. You are not learning a totally new language here. Keep your beloved syntaxes and keep the way you used to format your code, only remember that now you need to build upon the coding skills you already have.In case you have absolutely no knowledge of HTML and you want to start now, I advise you to start with HTML 4.01 and only when you master it move onto HTML5. Starting with the latest version is like learning to run before learning to walk – which is impossible as far as I know. HTML 4.01 still contains the basics of HTML5, therefore in my opinion you should have strong knowledge of former HTML versions in order to be able to master HTML5.
The upside of learning HTML5 now is that the new markup language works right away. You can basically do whatever you want with it today – and it is supported in all major browsers. From video to geolocation, local storage and microdata annotations, HTML5 is something we need to start using. If you are in the design business, sticking with HTML 4.01 is a mistake, because everybody will move on while you will remain behind.
HTML5 is definitely here to stay. It is created to sustain today’s necessities and especially because it is in continuous development, it will be able to sustain the changes that will happen in the industry for quite some time. One of the reasons behind HTML5 taking so much time to develop is because the W3C had to analyze lots of factors and think of the future. They took their time and finally delivered something that can easily be labelled as a high-quality product.
Examples
In order to show you how far HTML5 actually got, I will showcase some websites and applications made with the new markup language, so you can see how much you can actually do with it.1. Read is a HTML5 responsive theme made for WordPress. It is minimalistic, very simple to understand and use, loads faster than ever and it is not expensive at all.
