The first thing you need to do is make your HTML document conpliant ti the W3C web standards by including the full tag below as the very first line in your document.

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

Then in your CSS document for the #content add the following attribute for reference, you can remove it later.

border: 1px solid black;

This will give you a solid black box around your content to reference placement and size.

Finally remove the first two lines above the body element in your CSS document.
