go to this site and chk out the footer....

its always there...i mean kinda sticky or fixed....how to do this.....

use css.

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

also good for

.bottomright {bottom:0 right:0 }
.menu {right:0; top:100px; width:15%;}
<body><a name='top'></a><a class='bottomright' href='#top'>&uparr;Top</a>
<div class='menu'> Your menu </div>
<!-- 1000s lines of html code that scrolls the page -->
</body></html>

and assorted stuf with logos copyright notice and anything else you want to stay in one place when the text scrolls around it
