PLacing Transparent Flash over a HTML page

HEy all,

Im looking for anyone who knows how to do the following!!

Have a standard html site with what ever info inside…

And be able to place a transparent flash animation over it!
so that, once its loaded, or after a cirtian ammount of frames it
plays over the top the the page, does its business, and then,
dissapears after is finished!!!

Ive seen it used quite commonly, but have never worked out how!

Any help would be greatly appreciated!!

Thanks Kirupa!
