Hi there, I am having a big problem in CSS, and I don't usualy require for help but now it's or asking, or giving up so Well, basicly what I want to achieve is a FIXED vertical sidebar (like the facebook one), using 100% of the height, and including 3 submenus. 1 - Height: fixed amount of pixel (should not be scrollable) 2 - 60% of the rest of the height (will contain the notification so it has to be scrollable) 3 - 40% of the rest of the height (will contain the online buddy so it has to be scrollable) This is what I ve done until now: http://jsfiddle.net/CrqLn/ I have also made an image of what I am trying to achieve so that you can understand better: Well, I hope you can provide me some help cause I have no idea how to fix this. Thank you very much ! TheCM.
