Is there a way to use straight HTML or CSS (no perl, php, javascript,
cgi) to create a web page that has variables in it, like so:

     <body>
Today's winner is <var=WINNER/>! Congratulations, <var=WINNER/>! 
Sorry, <var=LOSER/>.
     </body>
and then have a separate document that has variable definitions, like so: 

WINNER: Dogbert Comicdog
LOSER: Dilbert Comicman

So that the web page, when rendered by a browser looks like so:

Today's winner is Dogbert Comicdog! Congratulations, Dogbert Comicdog!
Sorry, Dilbert Comicman.

Thanks for any suggestions!

Perhabs you might have a look at server-site-includes (ssi). I think it's 
possible to do such things with these (there are, if I am right, some
include-commands to include another file in your document, what would be 
exactly what you were looking for). Though, you have to enable them in
your webserver (probably apache). Php, etc would also do the trick.
Php is probably your best bet. There is a book called PHP and MySQL Web Development (Luke Welling and Laura Thomson) in which the first example you work through shows how to present conditional information on a web page. The php script looks like this: 

<h2>Order Results</h2>
<?
  echo "<p>Order processed at ";
  echo date("H:i, jS F");
  echo "<br>";
    $totalqty = 0;
    $totalamount = 0.00;
      define ("TYREPRICE", 100);
      define ("OILPRICE", 10);
      define ("SPARKPRICE", 4);
  $totalqty = $tyreqty+$oilqty+$sparkqty;
 $totalamount = $tyreqty * TYREPRICE
                 + $oilqty * OILPRICE
                 + $sparkqty * SPARKPRICE;
  $totalamount = number_format($totalamount, 2);
  echo "<br>";
  echo "Items ordered:        ".$totalqty."<br>\n";
if( $totalqty == 0 )
{
   echo "<font color=red>";
   echo "You didn't order anything on the previous page!<br>";
   echo "</font>";
}
else
{
  echo "<p>Your order is as follows:<br>";
  echo "<br>";
  echo $tyreqty. " tyres<br>";
  echo $oilqty. " bottles of oil<br>";
  echo $sparkqty. " spark plugs<br>";
  echo "<br>";
}
echo "Subtotal:             $".$totalamount."<br>\n";
  $taxrate = 0.10;  // local sales tax is 10%
  $totalamount = $totalamount * (1 + $taxrate);
  $totalamount = number_format($totalamount, 2);
  echo "Total including tax:            $".$totalamount."<br>\n";
?>
</body>
</html>
