Odd issue changing background for specific pages.

I am trying to change the background of just one page in particular. I found this in a post that is closed here as a solution to my issue:

change the body tag in your page.php file to this
<body<?php if(is_page(‘about’)) echo ‘ class=”about”‘;?>>

This will add class=”about” to the body tag only on the about page

in your stylesheet add this
body.about { background-color: #color-code; }

However, when I do this, it only changes my background to a blinding white. No matter what color I stipulate, or leave the text black. It does this for all pages, not just the one defined by the code.

Any help would be deeply appreciated. Here is the temp URL where the site is being hosted: http://www.testjustin.comze.com

If anyone needs me to upload snippets of the different .PHP files I have, just let me know.

Again, thanks!
