1. CSS page-break properties

    Properties to control the way elements are broken across (printed) pages.

  2. display: flow-root

    The element generates a block container box, and lays out its contents using flow layout. It always establishes a new block formatting context for its contents. It provides a better solution to the most use cases of the "clearfix" hack.

  3. Picture-in-Picture

    Allows websites to create a floating video window that is always on top of other windows so that users may continue consuming media while they interact with other sites or applications on their device.
