Implementing .swf file through css

1

I was wondering how can I implement a Flash movie through a CSS file? I’m doing a friend a favour with his site, but the person who original made the site for him did it mostly through CSS and Divs. I’m lost, confused and not too familiar with this, can someone help me :smirk:

Here’s the coding from the CSS file:
#header-wrapper #header {
width: 698px;
height: 68px;
background: url(images/home/header.gif) no-repeat top left;
padding: 0;
margin: 0;
text-indent: -1000px;
}

Thank you in advance
