Quick easy question regarding search button

[CONetWebDesign]

Please see http://www.dev2.designbyconet.com

 

Check out the 'search' button at the top right... it has a white bg on it, Ive tried removing this but to no avail. Its a .png with a transparent bg and Ive search every CSS I can to remove the background color but I cant find it..

 

Any ideas where it might be?

 

Many thanks in advance.

Look around line 582 of your global.css take the image out and change the background color to black

/themes/presenttree/css/global.css

 

input.button, input.button_disabled, input.exclusive, input.exclusive_disabled, a.button, a.exclusive, span.button, span.exclusive {
width: 120px;
background-image: url('../img/button-medium.png');
color:white;
}

 

This image is the background:
