This is a pure CSS changer, easy to use to change background:
Write "background:" so you can start editing it.
To add an image, write -> url('http://yourImageUrl.com/image.jpg')
To keep the image fixed as you scroll, write "fixed" after the url.
To change the positioning write "top" or "bottom and then "left" or "right".
Write "no-repeat" unless you want it all over the place.
Write the color in hexadecimals #123456.
Don't forget to add the semicolon (";") at the end!
Examples:
background: url('http://i49.tinypic.com/21971pg.png') no-repeat #cae2f7;
background: url('http://i42.tinypic.com/xmikjo.jpg') fixed top right no-repeat #fdcfbf;
