How do I vary the height of a frame depending on the content inside? (In easy terms)

use in frameset tag table height property as 100% it will work as you want and within that table you can put your data.

It didnt work. now, I just see the top portion of every page, the frame does not change height. =(

Any other suggestions

For main/index page frameset

<frameset rows="20%,*,20%">
<frame src="header.html">
<frameset cols="20%,*,20%">
<frame src="left.html">
<frame src="main.html">
<frame src="right.html">
</frameset>
<frame src="footer.html">
</frameset>
</html>


for main body page

<table height="100%">
<tr>
<td>Put your data here</td>
</tr>
</table>
