 * Hello, I’m trying to set the background image to 100% [here](http://justflak.com)
   so that when you resize the browser window the background image also resizes.
   I looked in the css files but couldn’t find where it is.
 * I looked through all the css files but couldn’t find it…..
 * forgot to add that I’m using the 2011 dark theme

 * You cannot resize a CSS background image. The best you can do is tile it.

 * you most certainly can
 *     ```
       html {
       	background: url('../graphics/some_image.jpg') no-repeat center center fixed;
       	-webkit-background-size: cover;
       	-moz-background-size: cover;
       	-o-background-size: cover;
       	background-size: cover;
       	} *
       ```
