Adding a Highlight to Links

[Cal]

How would I go about adding a slight gray highlight behind my links or changing the link color (read on before you answer)? I go to Xenforo.css in templates and I changed the link CSS....but all it did was change all the links on the forum home. I only want this to apply to the links within posts.

Anyone have any ideas?

Appreciated. That did the trick.
