Site URL: https://opinionx.co
I use iframes throughout our Squarespace site to embed interactive product demos, GIFs and videos.
On our main landing page (https://opinionx.co), we use an autoplay video with a white background that is intended to blend into the overall site background. For some users, however, Squarespace seems to add a border to 2 of the 4 sides of the iframe. I've tried a few tricks (overflow, frame border) but nothing seems to get rid of it.
4th screenshot is of an embedded stack ranking survey, where the border should all be light grey but that 2 sided dark border pops up again (like on the video iframe).
Anyone able to help?
