Background Video

In order to achieve an edge-to-edge/cover effect for our video, we position: absolute; it within a parent container. We give it a faux-height via a padding value on this parent’s ::before pseudo element. If you aim to have a 16:9 aspect ratio, this padding value would be 56.25% (9 / 16). Do not forget to add a video placeholder image that matches your desired aspect ratio. Use both .webm and .mp4 video file formats for the widest browser support.

The -overlay modifier class can be added to the outermost parent container div with the class .backgroundVideo. This will create an ::after psuedo-element that will add a color overlay to the video. A linear-gradient is added with this modifier, but the ::after can be updated to any single color if preferred.
