Has it really been four years since the buzzword “HTML5” came screaming across the sky and gave us every reason to believe in the power of JavaScript in the browser? Time flies when you’re writing code.

HTML5 is back on the tips of our tongues because the W3C committee finally decided it’s time to stop fiddling with the HTML 5.0 spec and move on to HTML 5.1. This marks a historic occasion because the HTML4 document was finalized in 1997. Time drags when you’re working on a committee.

Browser No. 1: Google Chrome

Chrome has the highest score on the HTML5Test — 523 for Chrome 42– and that says much about Google’s commitment to driving the HTML5 spec and producing one of the leading browsers. There are only a few check boxes left for the programming team to mark and a few points for them to earn.

The omissions are scattered throughout the chart, and there’s no easy way to summarize with a simple phrase. You’ll find a missing markup element here and an unimplemented graphics method there. All in all, Chrome is a dream for anyone committed to a broad set of tools for building user interfaces. If you want to use all of the new markups or form elements, Chrome is your best choice. There are very few gaps in the list.
