ASP.NET 4.0 content placement

I have a small site I'm building and it is based on new ASP.NET 4.0 Web Application template. I'm using the Site.css. There is a border around the content by default, but the size changes based the amount of content. I was able to make this border around the content a consistent size by adding a height attribute to the .main value in the Site.css as shown below.

.main
{
    padding: 0px 12px;
    margin: 12px 8px 8px 8px;
    min-height: 420px;
    height:650px

}

However, I have a copyright user control that is placed on every page and it floats to the end of the content, whereas I want it to either appear below the border line, or just above it consistently.

Has anyone figured out the best way of accomplishing this?
