Margins on the Page:
Lets say you 
  want more space around the contents of your page. You can do that with the margin 
  tags.
  You will need to set this differently for IE and Netscape. So add 
  both in to make it work.
  In the Body tag put in <body leftmargin="x" 
  topmargin="y" marginwidth="x" marginheight="y">
  
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> 
<html>
  <head>
  <title>Pony Pony Pony</title>
  <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">

  <body leftmargin="50" topmargin="50" marginwidth="50" marginheight="50">
  Here is the pony. Isn't she terribly lovely and kind. Oh yes, and she likes 
  carrots and bread. And long walks through the forest. She likes to chase the 
  squirrels and rabbits. Nipping at their precious little fuzzy tails.<br />
  <img src="pony.gif" /><br />When she was a little foal, she 
  had the softest fur. Like the color of natural sugar.
