Now when I do a CSS check, it does not work and say: Target: http://www.ajaxswimming.ca/index.php Please, validate your XML document first! Line 337 Column 83 Element type "td" must be followed by either attribute specifications, ">" or "/>". 11348 1 ot 2006-09-01 00:30:55 +0000 Apparently, your code does some user agent sniffing, and returns different pages to different user agents. When requesting the page with User-Agent: Jigsaw/2.2.0 W3C_CSS_Validator_JFouffa/2.0 (the identifier of the CSS validator), The page I get has the following markup at line 337 <td style="background:url(/templates/Default/images/mtdbgbot.gif)"class="slink" align="right"> Note the lack of space between " and class. Conclusion: avoid user agent sniffing as much as possible. It wasted your time (and mine). :)
