body
in the CSS.
Your css stylesheet would look something like this:
body { background-color: black; }
Note the semicolon ; after the color (black). Now all that goes inside the <style> and </style> tags. Of course, you can replace the color black with whatever background-color you'd like your web page to have. You can find some at my color chart
body
in the CSS.
Replace DIRECT LINK HERE
with the direct link of your image of course. Here's an example.
body { background-image: url('http://mypic.com/image/background.png'); }
To get a direct link, simply go to an image hosting site. I use Mypic and Photobucket. Mypic is easier to use, and you don't need an account, but Photobucket lets you keep track of all your images and bandwidth.
You'll have to add the attribute background-repeat: to the body element in the CSS. You can add different values depending on how you want your background image to tile. For gradient-based backgrounds, this is a must.

If you want your background to tile vertically instead of horizontally though, just use the background-repeat: repeat-y; instead of repeat-x;.
