1. CSS zoom

    Method of scaling content while also affecting layout.

  2. DOMMatrix

    The `DOMMatrix` interface represents 4x4 matrices, suitable for 2D and 3D operations. Supersedes the `WebKitCSSMatrix` and `SVGMatrix` interfaces.

  3. CSS Flexible Box Layout Module

    Method of positioning elements in horizontal or vertical stacks. Support includes all properties prefixed with `flex`, as well as `display: flex`, `display: inline-flex`, `align-content`, `align-items`, `align-self`, `justify-content` and `order`.

  4. rem (root em) units

    Type of unit similar to `em`, but relative only to the root element, not any parent element. Thus compounding does not occur as it does with `em` units.

  5. Streams

    Method of creating, composing, and consuming streams of data, that map efficiently to low-level I/O primitives, and allow easy composition with built-in backpressure and queuing.

  6. CSS3 2D Transforms

    Method of transforming an element including rotating, scaling, etc. Includes support for `transform` as well as `transform-origin` properties.

  7. CSS3 3D Transforms

    Method of transforming an element in the third dimension using the `transform` property. Includes support for the `perspective` property to set the perspective in z-space and the `backface-visibility` property to toggle display of the reverse side of a 3D-transformed element.

  8. URLSearchParams

    The URLSearchParams interface defines utility methods to work with the query string of a URL.
