CSS Level 3 Media Queries

In my humble opinion, the upcoming CSS Level 3 Media Queries are one of the major improvements in web development.

Yesterday I have implemented those in my web site so that it adapts to various browser window widths.

See them in action on Youtube!

Try it for yourself and tell me what you think :) (CSS 3 media queries are currently supported in FF 3.5+, Chrome, Opera, Safari and IE9+)
