Is there a reason you have embedded the container and content in the index.php file?

Yes. This is to make use of php to detect if modules are published left or right. External style sheets could have been used but would have been more server requests for what equates to a couple of bytes of code.

Hi Earthrat,
We have combined just a tiny amount of CSS into the PHP - just that which contains the column width information - Only the little snippet that pertains to your module layout will be publised - e.g. the source code for the demo home page at casenano.com shows:

<!--
#content {
padding-left:0px;
width: 500px;
}

#container {
background-image:url(/templates/polarbearpro/images/body.png);
}

-->

It really is a negligible amount of markup, as Bambii said, but if it concerns you, and you intend to use only one of the column configurations for your whole site (1,2 or 3), then you could easily strip out the dynamic php and move the column width css into template.css - It would take less than 1KB off your page load.

Let us know if you have any more questions.
