HTML5 and CSS3 has been known to web designers for many years but due to the lack of browser support it hasn’t been wildly adopted up until the release of Internet Explorer back in 2011. Internet Explorer 9 still doesn’t have complete support for HTML5 and CSS3 but IE10, which hasn’t been released yet, will support more elements including CSS transitions, transforms and have full support for offline web applications and form validation. Other browsers such as Google Chrome, Mozilla Firefox and Opera have better support but as yet there is no browser that has full support yet due to the fact that the specification is still a working draft itself and is estimated that it will not be reaching full specification until 2014. However don’t let this deter you from using it, you can start using HTML5 right now so kick it off with some valuable resources.
On another note I haven’t included the wonderful Smashing Magazine. They have produced a wealth of informative and inspiring articles which have helped all users get a foothold in the creative environment we call web design. For those of you that haven’t heard of Smashing Magazine then you are really missing out.
Of course I have merely touched the surface on the wealth of resources available. Feel free to add some of your own.
