I would calculate the offset position from the window, remove it from its parent and attach it to the body.

Eg:

var left, top;
left = jQuery(element).offset().left;
top = jQuery(element).offset().top;
jQuery(element)
  .appendTo('body')
  .css({
    'position': 'absolute',
    'left': left + 'px',
    'top': top + 'px'
  });


You can't. overflow: hidden; Hides content outside the element. Period.

z-index applies to absolute AND relatively positioned elements, just differently, despite what someone else said.

EDIT You could put some padding-top on that particular div, if you can live with that padding, that is. The div would need to be a little wider, too.

EDIT 2 As others have stated, though position: relative; and position: absolute; are probably more common, yes, z-index works with position: fixed; also, just not for position: static; I overlooked those.


Just a correction: z-index applies to position: relative, position:absolute AND position:fixed. To answer the original question - there's no way in CSS to make a child of an overflow: hidden element show it's contents outside the parent borders, you must change the hierarchy.


I assume you don't need .coda_bubble to be a child of .overflow. If not then move it out and create a positioning div to hold both children.

The z-index property ONLY work in elements that have position option set to absolute or relative.

In other words you ALWAYS need positon to work with z-index.


The z-index property applies to those elements having position set to absolute. Try this css instead:

.coda_bubble{
  position:absolute;
  z-index:100;/****NOT WORKING*******/
}
