How would one translate this for use in XDPro6. It is a gradient on repeating x across the page followed by a centered background in the top centre that fits seamless.

Code:
html {
	background: #73ADD7 url(../images/gradient.gif) repeat-x;
}
Then a centered logo in the background as well like this
Code:
body {
padding: 0;
	margin: 0;
	
	background: url(../images/sky.jpg) no-repeat center top;}
Any ideas?

Cheers
