css/jquery尺寸和IE和Chrome在视图->缩放时的绝对定位问题!= 100%

I have a strange problem with absolute positioning and sizing elements to fit around a div. I have some div that's set in position and size on an existing page (it's given to me). I want to adorn it from the left and bottom with two divs, so that they'd "hug" it and create an "L" shape. I need to do this dynamically, as the div size and position change in the course of the normal usage of the web page.I have a strange problem with absolute position
