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

while implementing the image replacement technique like above, there are some rules to go with css to get it work on IE browsers.

css declaration:

text-indent:-9999px;
text-transform:capitalize;


font-size:0;
display:block;
line-height:0;

font-size:0 is used to reduce the font size and works well in IE7. But even after adding this line, you would notice a black line(which is basically the text) on the center of the button in IE6.

display:block Negative text-indent works in IE only if this is added.

line-height:0 Another fix for IE6.

text-transform:capitalize I don't know the exact reason of including the property, somehow it fixes the issue.

Hope this helps.
