Question

I found this Page and after resizing windowwidth, it totally changed its css-values. I thought of Javascript, but it even does with JS disabled. If you resize the Page, it changes the width in 3 steps. The computed css-values shown by firebug or chrome are not affected, but you definitly see the change. I searched for some kind of media-query or something else, but there was nothing. Hope someone understands what’s going on =) I’d like to use it instead of media-querys

Answer 1

They are actually using media queries. You can easily check it out by searching in their css for @media, there are plenty of matches.
