//  Overriding existing css is often much more of a pain than just figuring out how to
//  style something custom/new. Therefore we disable a lot of the core css so that we spend 
//  less time 'undo-ing' and more time 'doing'. The only ones left are the 
//  admin.css and system.css.

//  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 atck_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 the approach here. Choice is good.
