Help hiding css popup in IE

I am trying to create a custom Facebook Tab using iframes. Anyways, it has a popup when it first loads. However, this popup doesn't display correctly when shown in Internet Explorer.

I tried the below code so I could attempt to hind the popup altogether, but it didn't work.

<!--[if !IE]>
    -->开发者_Python百科 

#hidepopup {
   display: none;
   }

    <!--
<![endif]-->

With the popup code between <div id="hidepopup"> & </div>

Any suggestions on how to hide or resize it?

There are a few things going on here.

• The conditional used is a IE conditional directive specifying: if not IE, these are IE only so it is a bit backwards
• The conditional is incomplete the end comment happens immediately after the first condition.

Try This:

<!--[if IE]>
<style type="text/css">
   #hidepopup {
     display: none;
   }
</style>
<![endif]-->

<!--[if IE]>

<style type="text/css">
#hidepopup {
   display: none;
   }
</style>

<![endif]-->

Do not use ! because it means not IE and you have extra opening/closing tags for comments. Also you have not declared that it is style. Here is link to help you with conditional comments: http://www.quirksmode.org/css/condcom.html

Your second issue is that you are using jQuery for animating popup. Animations are changing display:none to display: block. So your special condition for IE is overwritten by script. here:

//transition effect
$(id).fadeIn(2000);
