Ringmark is a web-based test suite optimized for mobile browsers, but still functioning on desktop browsers as well. In three turns, the so-called rings, Ringmark determines the different HTML5 and CSS3 possibilities, then tells you which functions are safe to use.
The Three Rings Of Ringmark
The first ring, the browser has to run through, checks for basic functionality, such as CSS3 animations and transitions, 2D and 3D transforms and support for canvas. This first stage should be achieved by any modern browser, except IE. As no special mobile functions are checked during this test, any desktop browser should not have problems running it.
The second ring checks for more CSS3 properties such as media queries and special functions on mobile devices. This includes offline mode and device orientation as well as multi-touch events. The latter will make every desktop browser give up. It is safe to say that any browser successfully running through the second ring is capable enough for audio and video apps as well as 2D games and apps with webcam access. Browsers that manage to stand the third ring are best suited for any kind of HTML5 apps. This includes 3D games and messaging or video streaming apps.
Check the Support for Different Browsers
If you do not only want to test the capabilities of your own browser, but need to know more about the support of HTML5 and CSS3 in mobile browsers in general, you can check that in additional lists Ringmark has at hand.
These lists include recent android and iPhone browsers as well as chrome, opera and internet explorer in their respective mobile versions.
