Test with content

Code for this version is as follows:

CSS code (should go in blog layout template, but CAN be posted in a post)

<style>
.leftcolumn {
float:left;
width:70%;
padding:10px;
}
.rightcolumn{
float:right;
width:25%;
padding:10px;
border-left:2px solid red;
}
</style> 

Post template code to format a post as two columns:

<div class="leftcolumn">

MAIN CONTENT

</div>
<div class="rightcolumn">

SIDE CONTENT

</div><div style="clear: both;"></div>

To change the width of the columns you must change the width attribute lines in the CSS code. You can keep it as percentages as it is now, or change it to pixels. Here is an example with pixels. It is a very easy change, so feel free to play with it.

<style>
.leftcolumn {
float:left;
width:600px;
padding:10px;
}
.rightcolumn{
float:right;
width:300px;
padding:10px;
border-left:2px solid red;
}
</style> 

Filler text to make column longer:

Where did it all begin?

At four years old I started dancing tap ... but BEGGED my mom to let me quit. That ended my dance career. Later, I casually started line dancing in a bar  until they ran west coast swing lessons – and I got abducted into the world of partnership dance and never looked back! 

Filler text (I left it unformatted, but you can format it as normal)
