How can I place a div into the SCREEN (not page) center,
when the div is in an iframe,
and the div’s x position for being in the SCREEN center is
too far left for still being on the iframe page (div.x < iFramePage.x) ?
The iframe is in a table in the right row, and in the left row there is a navigation treeview.
Now my div should overlap the treeview, for being in the center…
How can I do that ?
You can’t. The contents of an iframe will never be able to “leave” the frame, instead, the iframe will get scrollbars.
No offense, but this sounds like a poor site architecture anyways. Maybe you should have a look at (lightweight) content management systems. Having that said, maybe you have a very very grace reason for this “architecture”?
