Flexbox Video Fiasco – Video Disappearing in Div When Centered

Design help General

I feel like I’m going a little crazy!

I’m looking to center a video on my site, and whenever I add it to the div inside of a section that has flexbox enabled, it completely disappears. You can add images and they respond correctly, but as soon as I add a video it’s gone. Any advice?

I believe you need to give the div block a defined width and height
