Thanks for your suggestion! I did not know about the text shadow css
property. I did some googling and found an interesting way of using
shadows all around the text to create an outline. For reference, here
is the css rule that I ended up with:
a[href] { color : black !important; font-weight:bold !important; text-
shadow: -1px 0 white, 0 1px white,
1px 0 white, 0 -1px white !important;}
