How do I get rid of background on a input.submit?

Question

Hello! I am currently trying to replace the input.submit button with an image. I have managed to do this successfully except there seems to be a background around the image which I want completely gone, and for it to just be the image.

Here is my css:

 {width:70px; height:40px; background:transparent url(images/shadow_search.png) no-repeat center top; overflow:hidden;} 

(I've tried background:transparent to hide it, as well as overflow hidden?)

thanks in advance

Answer 1

That'll be just the border.

selector { border: 0; }

Should do.
