Someone tell me what is wrong with my PostComment2 class that is not making the 'Respond' text white. I'm stumped. http://www.obsessedwithfilm.com
a:link { color:black; } is overriding your .PostComment2 a { color:#fff; } because it appears after it (put the .PostComment2 below it). That's why you should always put rules for common elements (h1, h2, h3, h4, a, div, blockquote, etc) at the top of yourstylesheets and have your more specific rules (with classes/IDs) below.
sorry, I wanted to help you, but I'm not sure what the problem could be. I gotta say though, that is a great looking site, really really nice, you are going to do well with that.
