JQuery IE Margin / DIV Conflict

Having some issues with IE and how it is formatting my function… Works fine in Firefox.

Here is my function:

    jQuery('#live_feed').prepend('<div class="feed" id="post-' + entry.id + '">' + entry.html + '</div>');
            jQuery(div_id).fadeTo(0, 0,
              function () {

                  jQuery(this).css('margin-bottom', '20px');
                  jQuery(this).css('display', 'block');
                  jQuery(this).css('position', 'relative');
                  jQuery(this).animate({marginBottom: 20}, 1000, 'swing', function () {
                            jQuery(this).fadeTo('slowly', 1); 
                        });
              });

Any help much appreciated!
