To change the color of the box next to your logo, add the code in red to your stylesheet where indicated:
Code:
/*wrappers - page or section containers*/
#mainWrapper {
background-color: #ffffff;
text-align: left;
width: 100%;
vertical-align: top;
}
#headerWrapper {
background-color: #ff0000;
}
#headerWrapper, #contentMainWrapper, #logoWrapper, #cartBoxListWrapper, #ezPageBoxList, #cartBoxListWrapper ul, #ezPageBoxList ul, #mainWrapper, #popupAdditionalImage, #popupImage {
margin: 0em;
padding: 0em;
}
That will make it red. You can change the color code to whatever color you like.
