Text indent is not working in ie7

Question

I am working on a website and on the top navigation bar there is a search box, I applied the following css on the search submit button

#submit {
   background:          


        

Answer 1

If nothing else works exactly right, this does:

color: transparent;
text-indent: 0 !important; /* reset the old negative value */

So normal browsers use the negative text-indent, ie7 gets special treatment using conditional comments
