..a coloured scrollbar on your iframe bit? If you know what I mean?

When I try this code :

<style>
BODY{
scrollbar-face-color:#000000;
scrollbar-arrow-color:#000000;
scrollbar-track-color:#000000;
scrollbar-shadow-color:#000000;
scrollbar-highlight-color:#000000;
scrollbar-3dlight-color:#000000;
scrollbar-darkshadow-color:#000000;
}
</style>

It doesn't make the Iframe scroll bar coloured it just makes the page scroll coloured..

You have to put that code on each page that appears inside the iframe.
