I couldn't find the JavaScript that's making it work, but it looks
like it's adding a class to the postcomment div when the window's
scrollTop is equal to or greater than the div's offset top. The class
has a style declaration with position:fixed.
here is a quick and dirty way to do this (using div id="sidebar" as
the example). Probably better to add/remove a class, but just so you
can see what you might have to put in the class ...
$(document).ready(function() {
var sbOffset = $('#sidebar').offset().top;
$('#sidebar').css('top', '0')
$(window).bind('scroll', function() {
$('#sidebar').css('position', sbOffset > $(window).scrollTop() ?
'relative': 'fixed');
});
});
Keep in mind that this isn't going to work in IE6. For that, you'll
have to resort to some other tomfoolery.
