At the 2013 W3Conf I gave a talk about the browser compatibility site Caniuse.com. The talk consisted of two parts, starting with an explanation of how caniuse.com started, how it’s useful to developers, and what’s to come on the site. The next and larger part discusses top web features now supported by enough browsers that you can safely start using them without worry or guilt. Features include CSS Tables, Pseudo-element & generated content, CSS counters, CSS outline, sessionStorage & localStorage, hashChange event, text-overflow, and Data URIs. Lesser supported but related features are also addressed.
The talk was recorded (together with all other W3Conf talks) and can be viewed here:
