Full background image on the web page

I found a method on a website on how to fill the entire web page with a background image. I used the recommended method but the other elements in the html file do not display.

What am I doing wrong?

Forgive me because I am newbie when it comes to CSS and HTML?

I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Hello Cookiejar,

Add the below code on top in final_layout.css

html { 
  background: url(image_bkgrnd2.png) no-repeat center center fixed; 
  -webkit-background-size: cover;
  -moz-background-size: cover;
  -o-background-size: cover;
  background-size: cover;
}

Open in new window


Also I updated and attached the html page and CSS, you can download the attached zip file.
