Border and Background in ad preview in Banner Animation Posted June 7, 2019 Thanks for the confirmation on the transparent background, that makes sense and I'll be sure to set a background color going forward. Also, using border-box makes a ton of sense, can't believe I missed that. I ended up using a div within my body and accounting for my border width when creating the size, which also worked. In the future, I'll just be sure to get my resets like border-box in order before I get going on my ad. Thanks!
