One modern, attractive way of placing a lot of content into a little space is by using a tab system. This tutorial will show you how to create a sexy, animated tab system complete with CSS sprites, cookies, and animated tab swapping.
Go over to NetTuts and check it out!

Great tutorial, I know you are a moo tools guru, but it would be a cool do a j-query version of this maybe… at somepoint (fingers crossed).
Nice one David, great tutorial. really great!
Hey David, sleek simple little effect :)
What I noticed though, is when I switch off javascript it does still work however it is really slow. From click to action about 4-5 sec.
I used Firefox 3.5.7 and switched javascript off in the browser itself, not the webdeveloper toolbar or something similar.

Hi David!
Could you help me with this script?
I need the possibility to “open/close” the tabs – and that all tabs are closed at the beginning when the Site loads…
Please!!! I really need help with this!!!
Thank you!!
