It’s always nice to find Video.js in the wild, but this article from The Guradian is an especially cool use case. Most of the players don’t use controls at all, but rather play/pause based on the user scrolling the page. The ones that do use controls are styled with a white on light gray theme that matches the rest of the page really well.
The article begins with a full-width video that includes controls.
Most of the videos are short dialogs that are triggered based on scrolling to a certain point in the page. These have no controls other than an external play/pause button.
