To fix that, in skin/smart_template/css/altskin.css
Below...
Code:
/**
* General tags styles
*/
Insert...
Code:
html,
body
{
background-color: transparent;
}
Then the background is controlled by your theme css file.
eg.
Code:
body {
font-size: 76%; /* Base Font Size : 76% - 90% */
font-family: Arial, Helvetica, sans-serif, "Lucida Grande", "Lucida Sans Regular";
background: #E9E9E9 url(apple/body_bg.png) top center no-repeat;
background-attachment: scroll; /* scroll or fixed */
}
