Trimming Long Outlines in Firefox
Nathan Smith had a post awhile back about those stray outlines in Firefox 1.5 due to using a negative value for
text-indent used in image replacement. I initially passed on the article as I like users to still receive the default feedback.
Then, in trying to resolve the problem on my own site, I tried using
overflow:hidden on the replaced link and suddenly the outline fit into place. In referring back to the article to see if I missed something, it appears that Trovster mentions this in the comments. I just wanted to highlight this fact as I seemed to have missed it.
Maratz documents this issue well on his site (who's article I also seemed to have missed at the time).
