full page height in kubrick? please?!

see: https://crossfitfortmeade.com/?page_id=1526

can’t get the #content tag to be full page height w/o setting pixel value which obviously causes all sorts of other issues. had the same problem w/ sidebar which was solved w/ :

#page {
text-align:left;
background-color:#FFFFFF;
width:900px;
border:0;
margin:0 auto;
padding:0;
overflow:hidden;
}

#sidebar {
font-family:”Courier New”, Courier, monospace;
font-size:12px;
width:225px;
margin:0px 0 -5000px 650px;
padding:20px 15px 5000px 10px;
background-color:#fff;
}

it won’t work w/ content – it overlaps the footer. ideas?!
