jQuery Keep Div on Bottom of Screen

How to keep div on screen (at the bottom or top) using jQuery.

This can be achieved with basic CSS but if this fails there is some jQuery/JavaScript you can use to
potentially fix the problem of keeping a div on the bottom of the screen even when scrolling.

.bottom { position:fixed; position:absolute; right:0; bottom:0; padding:0; margin:0; }

/*IE FIX*/
.fixie {
  left: expression( ( - jsrp_related.offsetWidth + ( document.documentElement.clientWidth ? document.documentElement.clientWidth : document.body.clientWidth ) + ( ignoreMe2 = document.documentElement.scrollLeft ? document.documentElement.scrollLeft : document.body.scrollLeft ) ) + 'px' );
  top: expression( ( - jsrp_related.offsetHeight + ( document.documentElement.clientHeight ? document.documentElement.clientHeight : document.body.clientHeight ) + ( ignoreMe = document.documentElement.scrollTop ? document.documentElement.scrollTop : document.body.scrollTop ) ) + 'px' );
}

//note you MUST set a height property for it to work correctly
if ( $.browser.msie ) {
	div.css({position: "absolute", width: jslide_width, right: 0, height: 100});
	div.addClass('fixie');
} else {
	div.css({position: "fixed", width: jslide_width, right: 0, height: 100});
}
