What’s a good, simple HTML / CSS text editor for Windows with up-to-date autocompletion for CSS3 and HTML5?

Answer by Jacob Nelson:

Aptana Studio 3  should be good enough for you.

This supports html5/css3 with normal and html5 boilerplate template and have good autocompletion features.

Another editor you can try is NetBeans

Both these editors have multi language support.
ie; these editors support other languages like Java, PHP, PERL etc.

The best part is, These Editors are free.
