I have a header image that I want to vertically align to the top of the page and a footer image that I want to vertically align to the bottom of the page. So I try putting this between them:
<table width="800" height="100%">
<tr>
<td>
</td>
</tr>
</table>
The result is: NOTHING! The table does nothing. You can’t see it. So the footer is right below the header.
