Thank you Virtual and Shilon,
I tried that (with the semi-colons at the end) but it didn't work (and the browsers that were working fine stopped displaying the background image - I think because I took out the overflow element)...I've tidied up the code to:
#content .distributors {
background-image: url('../img/bg_content_awards.gif');
background-repeat: repeat-x;
margin-top: 20px;
margin-bottom: 20px;
padding-left: 35px;
overflow: hidden;
}
BTW, you can see the html in the site in http://www.katpak.com/cat_toilet_distributors.html if it's of any help.
