need help positioning

hey guys,
im workin on a site and i have it basicly all done, but i want everything to dock to the lower left hand corner. i tried using absolute positioning left 0%,bottom 0%, but it goes too far down and you have to scroll down to get to it. so if anyone knows how to position it in the lower left handcorner without it going too far down, please share. thanks!

position:absolute;
left:0%;
bottom:0%;
margin-top:-YYpx;


YY = The size of the div you want to align.
