Embed prototype with device only and no background?

[Jennifer_Chung]

Hi I’m trying to embed my prototype on my portfolio (using WIX). I was able to do so BUT the black background shows… Does anyone know a way to show the device only… without the black background?

Thank you!

JK I realized I can just make the background for the prototype white…
although there is still a bit of a faint border around it (on left and right side only actually) - if anyone knows how to get rid of that, that would be awesome!
