Transparent Iframe Body

I need to have a (crossdomain) iframe with dynamic width and height.

My question is, Can I create an iframe with 100% size and a transparent background that will show the parent of this iframe, behind it ?

Can I attach a css property or a transparent gif for the iframe background to make that effect ?

Thanks.

Solution 1:

yes you can (if i understand your question correctly)

heres the code if you have edit access to the iframe content put this in the head (of the iframe)

<style type="text/css">
 <!-- BODY {background:none transparent;}-->
 </style>

and then embed the iframe like this

<iframe src="frame.htm" allowtransparency="true">

Solution 2:

By inspecting the iframe page you might find out there is color on some parts of the page. My suggestion would be to start from the highest component when adding the transparency:

html {
  background-color: transparent !important;
}

And then in the iframe element:

<iframe src="www.." allowtransparency="true">
