Center Popup Box Horizontally

**dmwhipp** · 06-02-2011, 09:51 PM

1) Script Title: Popup Box (DHTML Announcement Box)

2) Script URL (on DD): http://www.dynamicdrive.com/dynamicindex11/abox.htm

3) Describe problem: I have this working on a test page of my client's site, but would like to have it centered horizontally: http://www.summerfoodflorida.org/index2.html

In addition to centering it horizonatlly, I would like to add a 5 second delay before the box pops up. I found a thread regarding this, but neither solution worked.

Thanks in advance,
Deborah
