frameborder and allowtransparency in CSS

[crmpicco]

<style type="text/css">
.iframe {
position: absolute;
top: 110px;
left: 712px;
z-index:2;
filter:"progid:DXImageTransform.Microsoft.Alpha(style=0, opacity=0)";
}
</style>

<iframe frameborder="0" class="iframe" allowtransparency="true"></iframe>



Is there a way to put both the frameborder="0" and the allowtransparency="true" into the CSS styling class 'iframe'???
