Browse All TopicsI am fooling around in Dreamweaver CS3 (No customer does not intend to upgrade at this point in time) doing stuff i am not qualified to do.
I have created a basic page using one of the CSS-templates (2 Column Fixed, left sidebar, header and footer).
In the main contend i have placed an iframe in which the customer wants various pages to open. So far all well and good. But, when opening a PDF, the menu gets placed "under" the PDF. Is there any way to get it to be placed above the PDF so it remains visible?

Then the iframe will suffer z-layer issues. As mentioned previously, if the pdf object size is manipulated by the browser, the browser reissues the z-layer index. There may be an undiscovered solution, however at this point only the problem has been discovered. When a pdf object in an iframe is resized, z-index is ignored and the browser redetermines it's layer index. The only 'solution' known at this point is to ensure the pdf fits into the iframe dimensions.

1. Set the i-frame to have a negative z-index for eg <iframe style="z-index:-99" ...
2. The iframe dimensions and the pdf dimensions must be compatible. Resize each so that the iframe can always comfortable fit the pdf. iframes develop z-layer issues when the browser dynamically resizes it to fit the window displaying it.
