CSS Style Sheets help

Hello.. i'm trying to make a style sheet like this:

#Menu {
COLOR: #FFFFFF;
BACKGROUND-COLOR: #7093DB;
LEFT: 0px;
TOP: 100px;
WIDTH: 150px;
}

looks great and everything, but i like it to be from the TOP (100px) to absolute bottom!

with this i mean, like margin bottom=0 i hupe you understand. this is just a menu, that will last as long the text in some other style sheet is..

so, i added HEIGHT: 100%; in the #Menu, but this isn't right. Can someone please tell me, with what must i replace that 100% by HEIGHT??

Thank you all

You wan't a menu from the most bottom to the top (-100px?), right? You'll likely need to get your hands dirty with Javascript and set it during document loads.

Check out http://www.javascripter.net/faq/browserw.htm to get window size. Didn't worked under IE5 for Mac (Mac NS 4.75 is ok probably all others too). It should work for any fourth generation browser anyway.

okay.. now, i'm confused! there must be some other way to do that... i'm 100%... or not???
