override overflow:hidden with z-index
Am using coda_bubble jquery plugin, and i need to make my bubble pop out within an overflow hidden div. here is my sample code.
<html>
<head>
<title>Override overflow:hidden</title>
<link href="http://www.myjquery.co.uk/jslib/jquery_plugins/coda_bubble/bubble.css" rel="stylesheet" type="text/css" media="all" />
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js"></script>
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jqueryui/1.7.0/jquery-ui.min.js"></script>
<script type="text/javascript" src="http://www.myjquery.co.uk/jslib/jquery_plugins/coda_bubble/jquery.codabubble.js"></script>
<script type="text/javascript">
$(function(){
opts = {
distances : [40,40],
leftShifts : [0,0],
bubbleTimes : [400,400],
hideDelays : [0,0],
bubble开发者_StackOverflow社区Widths : [200,200],
bubbleImagesPath : "YOUR RELATIVE PATH TO SKIN FOLDER",
msieFix : true
};
$('.coda_bubble').codaBubble(opts);
});
</script>
<style type="text/css">
body{
margin:0;
padding:0;
}
#wrapper{
width:300px;
margin:200px auto;
}
.overflow{
width:120px;
height:80px;
overflow:hidden;
float:left;
}
.coda_bubble{
z-index:100;/****NOT WORKING*******/
}
</style>
</head>
<body>
<div id="wrapper">
<div class="overflow">
<div class="coda_bubble">
<div>
<p class="trigger">Trigger Bubble</p>
</div>
<div class="bubble_html">
[BUBBLE CONTENT]
</div>
</div>
</div>
<div class="overflow" style="overflow: visible;">
<div class="coda_bubble">
<div>
<p class="trigger">Trigger Bubble</p>
</div>
<div class="bubble_html">
[BUBBLE CONTENT]
</div>
</div>
</div>
</div>
</body>
</html>
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*******/
}
