For our church website we would like to have link at the top of every page that says something along the lines of "First Time Visitor/New to the Church". When they click on it it would bring down a small section of content giving them basic information on the church, etc. Possibly even a video greeting from the pastor.

I am however stumped by the way it is actually done in geeksandgod.com. The search feature (as an example) when you click the bottom (linked to #) the css display value changes from none to inline. However, I am having trouble how this all works together?

Can anyone provide a few pointers in the direction I should head to replicate the underlying actions?

Thanks,

Everette
