I need to overlay a "play" button on various video thumbnails. The 50% Absolute Positioning / Translate Up 50% trick worked great when I was using a traditional Row/Column layout.
I've recently moved to using a flex layout so that it is easier for me to rearrange the various thumbnails, or add a new one to the top. Using flex means a lot less copying and pasting around.
Anyway, I cannot get the play button overlay to work or center any more. I tried some relative positioning stuff, which works in Chrome/Edge but fails badly in IE.
Any help appreciated, thanks
