opacity a:visited

Question

I can\'t get opacity to work on a:visited hyperlinks in firefox or IE

If I set the background color of a:visited it will work fine, but the opactity will not set.

Answer 1

SEC7115: :visited and :link styles can only differ by color. Some styles were not applied to :visited.

This from IE's Developer Tools console. I'm pretty sure Firefox's shows a similar error.

Sorry. Not much can be done there.
