Responsive Embed

Hi I have used the responsive Embed and having a bit of a problem. I have a website slide show external web address and background on the external script is set to white. I always end up with grey around the box.

enter image description here

I have to blank out the image for copyright reasons but its that grey surrounding the Responsive Embed i cant work out how to get rid off.


Try using Chrome/Firefox Site Inspector to find out where it is coming from..

(right click on the loaded website...)
