This specificallly is not code but your design. Start by changing/correcting how you are getting the look: In your style sheet find this:
Code:
#headerWrapper, #contentMainWrapper, #logoWrapper, #cartBoxListWrapper, #ezPageBoxList, #cartBoxListWrapper ul, #ezPageBoxList ul, #mainWrapper, #popupAdditionalImage, #popupImage {
margin: 0em;
padding: 0em;
}
#logoWrapper{
background-image: url(../images/header_bg.jpg);
background-repeat: repeat-x;
background-color: #ffffff;
height:110px;
}
Change to this, dropping the solid color jpg and replacing it with the background color for the headerWrapper.
Code:
#headerWrapper {
background-color: #ca9acc;
margin: 0em;
padding: 0em;
#contentMainWrapper, #cartBoxListWrapper, #ezPageBoxList, #cartBoxListWrapper ul, #ezPageBoxList ul, #mainWrapper, #popupAdditionalImage, #popupImage {
margin: 0em;
padding: 0em;
}
#logoWrapper {
margin: 0em;
padding: 0em;
height:110px;
}
Additionally, I would remove the color block from your logo leaving your logo as just a seal/logo image. Some browsers will render the jpg/gif color slightly differently than the html color.
