i have a general idea on how this works but im not absolutely sure.
im referring to: http://www.joelspeasmaker.com/main.html
how does that grey bg load up from the bottom to the top and when you click on “info”, the text seems to be unravveling, how do you do that?
and another thing,
if you click on a button for example, how do you make it not clickable after a user has clicked it once already?
sorry for asking a lot of q’s but its been on my mind
