qooy script help

Hi guys, I need some help in coding for Qooy script, I bought the script and wanted to round up the corners of the white outline of the site and change back ground, where can this be done?

Site: qooy.com

Is there any way to make the script look like qooy.net? I would pay someone that could clone the theme of qooy.net

Thank you.

 

Would you like to know how qooy.net achieves their nice rounded corners?

The stylesheet used by qooy.net is style.css. Take a look at it. Specifically these two paragraphs:

#header {
	width: 820px;
	position: relative;
	height: 106px;
	background: #CCC url(images/header.jpg) no-repeat center top;
	padding: 0;
	font-size: 14px;
	color: #FFF;
}

Code (markup):

#footer {
	color: #FFFFFF;
	background: #CCC url(images/footer.jpg) no-repeat center top;
	clear: both;
	width: 820px;
	height: 55px;
	text-align: center;	
	font-size: 92%;
}

Code (markup):

In fact, just type these urls into your browser:
qooy.net/images/header.jpg and qooy.net/images/footer.jpg.

To do it there way, just create what you want in a graphics program. Photoshop, the Gimp, Inkscape, etc.
