Day of the Dead Remake in Webflow

I decided to remake one of my favorite website in webflow. It ended up looking great! There are a few things I learned; 1. Use columns instead of flexbox when possible because flexbox is more process intensive 2. Use relative position to create hover elements if it is not in the direct parent element (look at "follow the project" section to see further) I also have two questions; 1. How do you center the video background relative to the screen width? 2. How do you create an element that continually rotates?
