I\'ve got a height and width, and overflow:hidden so that specfic inner images are clipped
All the above is nice but nothing beats JAVASCRIPT.
(Using jquery).
So,
What I do is, get the original position of the element (relative to the page), optionally get the height or width, optionally append the element to the body, apply the new css rule position : fixed and finally apply the original position and optionally width and height.
