Hello, I am having trouble implementing CSS on my HTML page...

This is currently my CSS page:

Code:
#container
{
	width: 960px;
	min-width: 960px;
	padding-left:10px;
	padding-right: 10px;
	padding-top: 10px;
	padding-bottom: 10px;
	margin-left: auto;
	margin-right: auto;
	margin-top: 10px;
	border: 2px solid #000000;
}
