Change default background color of < embed > ?
Hello! I'm using the < embed > feature on a site that has a dark background. I modified my vanilla forums theme so that that the background would black like the site it's being embedded on but there's a problem: For a split second before all the text and buttons and stuff from vanilla forums appear, the area which it's being embedded in flashes white, as if the < embed > had a white background that doesn't get overwritten until the vanilla stuff loads. Help and ideas?
P.S. if you want to see the example on the site I'm testing it on, I can message you the link.
