Newbie question about Twitter profile widget

I'm a beginner trying to start a website for our local Livestrong Army. I tried to add the Twitter Profile Widget to my right sidebar, but since my CSS for that sidebar dictates that type should be black it's overriding the twitter (copy/paste code) which indicates it should be white. If you highlight the tweets you'll see that they're there. Any tips on a fix for this?

The reason it worked for you is because I deleted the type color property for my sidebar2 and that seemed to fix it. I wonder if that was a wise solution

 

Thanks! I still have a lot of work to do
