DIV positioning problem on IE

i have a problem for my layout... it shou开发者_如何转开发ld be simple but i just won't get it right. It works on firefox but not on IE .... :'(

Problem: the div leftBar and rightBar should be resizing to the content. If there is a lot of text, they should have the same height (therefor i used top and bottom on an absolute positioning) the content is all right and it works just the leftBar and the rightBar won't resize... thx for responding, regards marius

<div id="container" style="position:relative; width:100px;">
  <div id="leftBar" style="position:absolute; left:0; top:0; bottom:0px; width:10px;"></div>
  <div id="content" style="position:relative; margin-left:10px; margin-right:10px;"></div>
  <div id="rightBar" style="position:absolute; right:0; top:0; bottom:0px; width:10px;"></div>
</div>

Try to have height as auto style="height: auto;"
