How to remove black background

Thankyou for this, it has worked now.. however I had to make the change in the actual css file in the ftp as it wouldn't change in the Joomla template manager panel. Even though it saved the changes it wouldn't change, now that I changed it in the actual css file in the css folder and uploaded this it worked fine. Thanks again for your help.

Hi Ivan, further to changing background colour,instead of inserting a colour, I would like to insert an image as a background, repeated. Can you help me please.

Hi,

open layout.css of template and find this:

body {
margin: 0;
padding: 0;
font-family: "Trebuchet MS", Arial, Helvetica, sans-serif;
font-family: Geneva, Verdana, sans-serif;
background-color: black;
}

replace background-color: black; with:

background: Black url(<path of image>) repeat left top;

Many thanks for that Ivan.
Chris
