CSS for Hyperlinks in Accordion Plugin

I tried using the css code found via google in another user's question on changing the color on the text that happens to be a hyperlink. But the code isn't changing and I can't figure out what additional code needs to be changed so that my links are set-out with a different color than the main text. Here's the page where I've got the Accordion Plugin working:
