// New regions for blocks are easy to add. Just put it in here so you have a
// new place for extra blocks. The first part is the name of the variable to
// place into your page.tpl.php and the second part is the human readable
// name that will show up in your blocks administration.

// You may notice that I have not used the traditional right_sidebar and
// left_sidebar. The reason for this is I want people to break the mindset
// that the regions are only for sidebars. This theme does use them for such
// since I wanted to provide a template that had the proper CSS for
// compensating for appearing and disappearing sidebars.

// Personally, I hate constantly overriding Drupal stock CSS. I find it just
// adds to stylesheet bloat when making a completely custom look. That is why
// I have disabled most of it with this theme. The only one left is the
// admin.css since it really doesn't do a lot beyond formatting the columns
// and illustrating the where blocks are located.

// The format below should be pretty easy to figure out so you can even remove
// other module's default styles if you find that they are difficult to
// override. (Or for that matter, put one back in if you like the drupal
// stuff.) I have tried to put the most crucial styles into this theme's
// style.css so that you have a good starting point though. I even included
// the .clear-block class sinc ethat is a very handy class to have.

// One other caveat to this approach is that if you want to use the non-drupal
// style method, you have to use copyblogger_styles() in your page.tpl.php
// instead of the common $styles veriable. On the plus side, you can simply
// use the $styles variable if you don't like my approach here. Choice is good.
