css style "bottom:0" in dynamic <div>
I have an absolutely positioned element at the bottom of a container element. The problem is that the content of the container changes dynamically (javascript). In FF it still works fine, but IE7 (didn't test any others) seems to calculate the position of the element relative to the top of the container on page loading, and then doesn't update it.
examples:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE html
PUBLIC "-//W3C//DTD XHTML 1.1//EN"
"http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="he">
<he开发者_运维问答ad>
</head>
<body>
<div style="position:relative;"
onmouseover="document.getElementById('test').style.display='block'"
onmouseout="document.getElementById('test').style.display='none'">

rufaurhf refhwrew regfnwreug wurwsuref erfbw rebvwsrefg</br>
rufaurhf refhwrew regfnwreug wurwsuref erfbw rebvwsrefg</br>
<div id="test" style="display:none;">
rufaurhf refhwrew regfnwreug wurwsuref erfbw rebvwsrefg</br>
rufaurhf refhwrew regfnwreug wurwsuref erfbw rebvwsrefg</br>
rufaurhf refhwrew regfnwreug wurwsuref erfbw rebvwsrefg</br>
</div>
<div style="position:absolute;bottom:0;background-color:blue;">
rufaurhf refhwrew regfnwreug wurwsuref erfbw rebvwsrefg</br>
rufaurhf refhwrew regfnwreug wurwsuref erfbw rebvwsrefg</br>
</div>
</div>
</body>
</html>
and the opposite:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE html
PUBLIC "-//W3C//DTD XHTML 1.1//EN"
"http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="he">
<head>
</head>
<body>
<div style="position:relative;"
onmouseover="document.getElementById('test').style.display='none'"
onmouseout="document.getElementById('test').style.display='block'">
rufaurhf refhwrew regfnwreug wurwsuref erfbw rebvwsrefg</br>
rufaurhf refhwrew regfnwreug wurwsuref erfbw rebvwsrefg</br>
rufaurhf refhwrew regfnwreug wurwsuref erfbw rebvwsrefg</br>
<div id="test" style="display:block;">
rufaurhf refhwrew regfnwreug wurwsuref erfbw rebvwsrefg</br>
rufaurhf refhwrew regfnwreug wurwsuref erfbw rebvwsrefg</br>
rufaurhf refhwrew regfnwreug wurwsuref erfbw rebvwsrefg</br>
</div>
<div style="position:absolute;bottom:0;background-color:blue;">
rufaurhf refhwrew regfnwreug wurwsuref erfbw rebvwsrefg</br>
rufaurhf refhwrew regfnwreug wurwsuref erfbw rebvwsrefg</br>
</div>
</div>
</body>
</html>
Any ideas/workarounds?
This is a known bug, I just can't remember the details right now nor what it is called.
Can you try giving the container layout using zoom: 1?
Alternatively, try overflow: hidden on it.
I just found this: IE CSS Bug - How do I maintain a position:absolute when dynamic javascript content on the page changes
It is a workaround, but not ideal for my situation. I'm using jquery's slideDown() method on 'test', so I can only have the bottom piece readjust after the animation is complete, not as it progresses. Not very smooth.
Anything else?
