Authoring HTML5 in Emacs?

Question

What\'s the best solution for authoring HTML5 in Emacs? Is there a mode that will do conformance checking?

Answer 1

An easier to install solution may be web-mode. It definitely plays well with HTML5 and doesn't require you to jump through the XHTML hoops.

JavaScript and CSS blocks work as you would hope.

It also includes the ability to handle common templating languages like php, erb, handlebars, etc.

Check out http://web-mode.org for more details. It's available as a package, at least on MELPA.
