Hot to get rid of this div with the CSS?

<div style="width: 100%; text-align: center; margin: 5px 0 5px 0;">
<a href=""""" /></a>
</div><div id="hallinta"><a rel="nofollow" href="/wp-admin/"></a></div>
<div id="page">

I have tried to do it with this code:

div[style="width: 100%; text-align: center; margin: 5px 0 5px 0;"] {
display:none;
}

This code works in Opera, Crome, Firefox, but did not in IE??

Is there another way to get rid of this with CSS? Or how to get it work with IE?

Help me, please!
