What can we expect from HTML5 and CSS3?

Digital

So what are we going to be able to do with HTML5 and CSS3?

These 2 new implementations introduce a whole raft of new things that can be done with a web site rendering through a supporting browser, we’ll just look at a few of them in this article.

So in HTML5 we have the new <audio> and <video> tags that enable us to embed sound and video files into a web page without the need for an additional plugin such as Flash to play it, as it is all handled by the browser.

The <canvas> element is another significant change as it is a new element for displaying graphics, it is a container that once set on the page can be painted onto with Javascript. It has already been used to create some clever games which again do not require anything but the browser to run.

These 3 tags are particularly significant when it comes to sites that are browsed using an iPhone or iPad because of Apple’s decision that neither of these devices will have any support for Flash making the areas of sites that rely on it un-displayed to these users.

With CSS3 there are some things that are particularly useful to simplify the use of things like opacity and multiple backgrounds on elements as well as adding support for rounded corners and shadows without the need for images or Javascript.

With most of the latest browsers supporting many of the new tags and methods that have been introduced with HTML5 and CSS3 and even Internet Explorer 9 joining in, are we going to see a lot more sites being launched now that are built on these new elements?

One thing that is an issue with developing sites on the latest technologies is that many large corporate companies and public sector bodies still rely on the older browsers, usually one of the Internet Explorer versions. Some still only allow staff access via the generally loathed (at least by web developers) IE6. So if you’re developing a site with one of these groups being either the target audience or the client, then as useful as the fancy new might be you aren’t going to be able to use them.
