I'm working toward making a new site NN6 compatible, CSS-wise, and I'm having some trouble, specifically with classes. NN6 seems to ignore classes for both input and span tags. My CSS seems to be valid, because when I include it as part of a style property, the elements are displayed correctly.

Any idea what I could be doing wrong?

The site in question is at http://www.mittfirma.no/

Thanks in advance !
