For a tableless approach...
In admin/tools/define pages editor, select define_main_page.php and enter something like this...
Code:
<div class="home-left">
<h3>A Heading</h3>
<p> .. your text goes here ... </p>
</div>
<div class="home-right">
<h3>Another Heading</h3>
<p> .. your text goes here ... </p>
</div>
Then in the stylesheet...
Code:
.home-left {
height: 1%;
width: 47%;
float: left;
}
.home-right {
height: 1%;
width: 47%;
float: right;
}
Adjust the values as necessary. (height: 1%; is an IE hack.
)
You can see the result in my site, linked below.
