From a designer perspective... I just wanted to say DAMN! to the responsive CSS. :)

What did you like about it? I don't have vB5 yet, I'll look at it when it releases.

Just wondering the basics about the responsive CSS approach they took.

Is it similar to the Responsive CSS Grid frameworks like Bootstrap, Foundation, or something else?
