Make <Div> Opaque

Hi,

I'm looking (unsuccessfully so far) for a <div> tag property that make that hides other <div>'s beneath it:

My page is a dynamic scrolling (vertical only) table upon which I have a <div> table containing the headers and a <div> table that holds the tabled data. I am using the FlevOOware (shameless plug) Dreamweaver Extension that makes my header element scroll down the screen, maintaining position while the tabulated data scrolls beneath it, but the headers are transparent and the tabulated data is visible through the top layer.

Is there not a property to make my top div opaque??

Thanks in advance

I'm not familiar with the extension, so I don't know how the div is being treated with CSS.
If it's background has been set to transparent, you should be able to override it with an inline style:

<div style="background-color:#cccccc;"></div>

The extension deals with repositioning the div in relation to any scroll events, there are no 'transparency' properties being set.  I have tried your suggestion before posting but to no avail.

There are no CSS styles being employed in the page (as yet) as i am testing on a mockup version.

Problem is, that I currently have the page split across a mainpage (that contains the column headers) and an inline frame that contains the results. I want the header to be contained within the same page as the client has insisted that the headers be sticky when scrolling down through multiple records, this is fine if you have opacity, but i cant achieve,. hence the headers in different page (i know this sucks but hey it a solution.....

The problem with the table dimensions on the two pages is that the data table containing form elements (text boxes) that are editable, hence screen res comes into play when sizing the elements. If there was a way of specifying <td> width without being over ridden by the text type size then I'd be laughing. I just can't get the table sizes to match up on various screen res's :(.

Incidentally, this form is for IE6 users only. Dont worry about NS compat.......

Dunno if this helps, but the idea is to hide the layer2 div beneath the scrolling layer1....
