I wonder if you have how to change the css of an EXTERNAL iframe that already has a white background and black font...
if it is not possible, I would like to leave the opacity of the frame a little Transparent because my page is black and it is all white, then in case it would be very weak opacity and when you pass the mouse (Hover) it is in true opacity...
css or javascript... the current iframe code looks like this:
<iframe allowtransparency='true' class='classpadrao' frameborder='0' height='410' id='idpadrao' name='namepadrao' src='' width='100%'/>
this edge would be internal or external to the iframe?

@Leocaracciolo edge of any element on the page containing the iframe.
