Jquery - Facebook Like Alert/Popup Box_问答_开发者

I finally found the perfect popup style box for my facebook application, However it seems to behaving very strangely in IE. The bottom buttons hang to the right..

You can see it in action here

Been messing around with the css for a while but can't put my finger on it..

HTML

    <body>
<div id="main">
 <div id="btn">Load Popup</div>
 <div id="backgroundPopup"></div>
 <div id="popupContact">
  <a id="popupContactClose">Close</a>
  <div id="popup_head"><h1>WebSpeaks.in</h1></div>
  <div id="personal">Post to Profile<br><br><br></div>
  <div id="contactArea">
   <textarea id="text"></textarea>
  </div>
  <div id="buttonArea">
   <div class="SharingOptions_Text">
    <a href="#" style="color:#3B5998;">Send as a Message instead</a>
   </div>
   <div id="Sharer_btns">
    <input type="button" value="Share" class="s_btn"/>
    <input type="button" value="Cancel" class="c_btn"/>
   </div>
  </div>
 </div>
</div>
</body>

Jquery

<script type="text/javascript" src="jquery.js"></script> 
<script language="javascript">
function loadPopup()
{
 $("#backgroundPopup").css({"opacity": "0.1"});
 $("#backgroundPopup").fadeIn("fast");
 $("#popupContact").slideDown("slow");
}
function disablePopup()
{
 $("#backgroundPopup").fadeOut("slow");
 $("#popupContact").slideUp("slow");
}
function centerPopup()
{
 var windowWidth = document.documentElement.clientWidth;
 var windowHeight = document.documentElement.clientHeight;
 var popupHeight = $("#popupContact").height();
 var popupWidth = $("#popupContact").width();
 $("#popupContact").css({"position": "absolute","top": windowHeight/2-popupHeight/2,"left": windowWidth/2-popupWidth/2});
 $("#backgroundPopup").css({"height": windowHeight});
}

$(document).ready(function()
{
 $("#btn").click(function()
 {
  centerPopup();
  loadPopup();
 });

 $("#popupContactClose, .c_btn").click(function()
 {
  disablePopup();
 });

 $(document).keypress(function(e)
 {
  if(e.keyCode==27)//Disable popup on pressing `ESC`
  {
   disablePopup();
  }
 });
});
</script>

Any Idea?

You have specified a bottom position . For IE7 you also need to explicitly specify a left or a right position

#popupContact #buttonArea{
    background:#F2F2F2;
    border-top:1px solid #CCCCCC;
    height:34px;
    margin:0px;
    position:absolute;
    bottom:0px;
    left:0px;
    width:100%;
    padding-top:5px;
}
