I've done exactly as you suggested to armylnablue, and I still get the "Oops, try again. Did you remember to set your link's text-decoration to none;?" error message.
This is what my CSS code looks like:
font-family: Verdana, sans-serif;
font-family: Garamond, serif;
border: 1px solid #4682b4;
I can't figure this out.
