You know you can manage to redraw an element with single browser reflow. Instead of using .style.property … you can simply add all CSS properties you’d like to change with simply appending to style.cssText property.

var csstxt = $('#selector').css('cssText') + ';top:100;left:100;border:1px solid red;color:#f00;';
$('#selector').css('cssText', csstxt);

That code is a replacement for

$('#selector').css({
   left : '100px',
   top : '100px',
   border : '1px solid red',
   color : '#f00'
});

enjoy!
