Css align to bottom of page

Question

I want my footer to always be on the bottom and move to adjust to the size of the content inside the page. Right now I have dynamic content that covers the footer because it's to much content.

How can I fix my CSS:

div#Footer {
  width: 100%;
  height: 80px;
  padding: 1px;
  -moz-border-radius: 35px;
  border-radius: 35px;
  background-color: Black;
  color: #ffffff;
  position: fixed;
  bottom: 0;
  text-align: center;
  margin-left: auto;
  margin-right: auto;
}

Answer 1

This is a simpler solution.

#footer {
    bottom: 0%;
    position: fixed;
}

#footer {   
   position:fixed;
   left:0px;
   bottom:0px;
   height:30px;
   width:100%;
   background:#999;
}

/* IE 6 */
* html #footer {
   position:absolute;
   top:expression((0-(footer.offsetHeight)+(document.documentElement.clientHeight ? document.documentElement.clientHeight : document.body.clientHeight)+(ignoreMe = document.documentElement.scrollTop ? document.documentElement.scrollTop : document.body.scrollTop))+'px');
}
