Does IE8 support HTML5 and CSS3?

Question

I have requirement where the client needs their website to be developed in html5 and css3. However it seems like ie6, ie7 don't support HTML5 and CSS3. The client said that HTML5 and CSS3 is supported in ie8, but I need to know to which degree it is actually supported.

Answer 1

• No browser supports all of HTML 5 or CSS 3
• Many browsers (including IE8) support some features added in HTML 5 or CSS 3
• All browsers support some of HTML 5
• All mainstream graphical browsers support some of CSS 3

Worry about what you want to achieve, then look for the optimal way to achieve it. Don't start with the tools available and then try to find a use for them.

Develop for the lowest common denominator and then progressively enhance from there.

Answer 2

Try to look at caniuse or html5test websites.
