Background image ok in IE6 but not in firefox

Hi people,

I need some help on adding a different background image to 3 different content pages.

I have tried adding an internal css style to each content page which works perfectly in IE6 but the background image is very small and is only half the size in firefox.

Here's the code I added to one of the content pages:

<meta http-equiv="Content-Style-Type" content="text/css" />
<style type="text/css">.contentpaneopen{


background-image: url(../GT/templates/JavaBean/images/content/targ_logo.gif);
background-repeat: no-repeat;
background-position: 0px 0px;
background-attachment: fixed;
background-color: transparent;


width: 604px;
height: 435px;
padding: 0px;

display: block;
font-size: 48pt;

text-align: left;



}</style>

Any ideas why FF can't understand the css style? Is there anything I can do to fix it up?

any ideas will be much appreciated.

A:
try getting rid of background-repeat: none;

Thanks for your quick reply. I have deleted the line as suggested and it has definitely helped. FF is showing exactly the same as in IE6. Only now I have the problem of the background tiling. Is there another way to stop the image repeating?

Also, how could I reference the css externally, either to my template or perhaps to another css sheet.

I have tried the following;

<css>
<filename>url(../GT/templates/JavaBean/css/content_css.css);</filename>
</css>

didn't work,

I have also tried;
<LINK href="../GT/templates/JavaBean/css/content_css.css" rel="stylesheet" type="text/css">

but alas it again hasn't worked.

Ok, the following code solved the problem. Not quite sure why, maybe someone could explain it to me.

Nonetheless, in case it can help anyone else the following code was displayed as required in both IE6 and Firefox 1.5.

<meta http-equiv="Content-Style-Type" content="text/css" />
<style type="text/css"><!--
.contentpaneopen{

postition: absolute;
top: npx;
left: npx;
width: npx;
height: npx;
z-index: 1;

background: url(../GT/templates/JavaBean/images/content/targ_logo.gif) no-repeat;


width: 604px;
height: 435px;
padding: 0px;

display: block;
font-size: 48pt;

text-align: left;

}
