non PHP question html/javascript

I know the < center > tag centers content horizontally, but how do I make the page center vertically?

Thanks

Easy, make the whole page with everything inside of one big table. It wont affect the rest of the page by having it in a table, so do this.

at the top of the page put..

<HEAD><TITLE> title. </TITLE></HEAD>
<body>
<table border=0 width=100% height=100%>
<tr><Td width=100% height=100% valign=center>

and at the bottom of the page

</td></tr>
</table>
</body>
