1. CSS display: contents

    `display: contents` causes an element's children to appear as if they were direct children of the element's parent, ignoring the element itself. This can be useful when a wrapper element should be ignored when using CSS grid or similar layout techniques.

  2. CSS Grid Layout (level 1)

    Method of using a grid concept to lay out content, providing a mechanism for authors to divide available space for layout into columns and rows using a set of predictable sizing behaviors. Includes support for all `grid-*` properties and the `fr` unit.

  3. CSS Grid Lanes

    CSS Grid Lanes extends CSS Grid to create layouts with columns *or* rows (not both), allowing mixed aspect ratio content to pack neatly (also known as "masonry" or "waterfall" layout).
