Here's what I'm looking for. The intro/splash page is void of content except some graphics and the "enter" button. Below:

--------Enter--------

onclick would split the top and bottom revealing the main page underneath.(and vice versa closing it), like so:

======Enter=======

to

---------Enter---------

content content
1234567890

-----------------------



I know there is some dHTML that allows me to do this, but i'm having a bitch of a time hunting it down. If anyone knows, or could just post the general code for it.. I can edit the rest to fit my site.
