I just stumbled on a cool site – html5readiness.com. The site displays a break down of browser support for HTML5 and CSS3 (Canvas, SVG, GeoLocation, Transforms, Border Radius, etc). The browsers included for 2010 are IE 7, IE 8, IE 9, FireFox 3.5, FireFox 3.7, Opera 10.50, Safari 4, and Chrome 4.
I wasn’t surprised to find that Safari and Chrome have the most HTML5 and CSS3 support (since both use the webkit engine). Firefox support for HTML5 and CSS3 is not far behind Safari and Chrome.
I was not surprised to find that Internet Explorer lags far behind (although IE 9 adds support for SVG, Video, SVG as Background, Media Queries).
I was very surprised to find that HTML5 and CSS3 support in Opera 10.50 rivals that of FireFox.
Anyway, if you ever need to know what is supported by each browser, take a look at html5readiness.com.
P.S. I wonder why Safari and Opera aren’t used as much as Firefox, Chrome and IE. Safari can be used with a Mac or PC, but appears to be used primarily by Mac users. Chrome has been around since 2008 and already has 5 times as many users as Safari (see browser stats).


For posterity, though, w3schools.com even says on their own site:
“W3Schools is a website for people with an interest for web technologies. These people are more interested in using alternative browsers than the average user. The average user tends to use Internet Explorer, since it comes preinstalled with Windows. Most do not seek out other browsers.
These facts indicate that the browser figures above are not 100% realistic. Other web sites have statistics showing that Internet Explorer is used by at least 80% of the users.”
$this->should_be_mentioned();
I haven’t seen the 80% stat in quite a few years. I’d like to see where you found that stat. I found another site that shows IE at 53% and shows that Chrome is used almost twice as much as Safari and over 4 times as much as Opera:

the best thing about IE8 is that it is quite stable than previous releases of Internet Explorer’.-
the safari and chrome are the reliable browsers which are supporting the cascading style sheets.
i have been following the news and reviews of googles web browsers,chrome.It is an open source project. the new thind added in this by google is javascript engine.
CSS3 is easy as compare to CS3…
Thank you for the post..
