<BODY> </BODY>
The BODY tag contains the actual contents of your page. After the HEAD commands you put this string:
<BODY BACKGROUND="BGimage.gif" BGCOLOR="#RRGGBB" TEXT="#RRGGBB" LINK="#RRGGBB" VLINK="#RRGGBB" ALINK="#RRGGBB">
This tells the browser that the background image is BGimage.gif, and if this image can't be found then the background should be the RGB value you selected (put this in place of RRGGBB). Text, links, visited links, and active links should be the specified colors.
After this string you put the contents of your page, and after you are finished with the contents put </BODY>
