1. selector list argument of :nth-child and :nth-last-child CSS pseudo-classes

    The newest versions of `:nth-child()` and `:nth-last-child()` accept an optional `of S` clause which filters the children to only those which match the selector list `S`. For example, `:nth-child(1 of .foo)` selects the first child among the children that have the `foo` class (ignoring any non-`foo` children which precede that child). Similar to `:nth-of-type`, but for arbitrary selectors instead of only type selectors.

  2. Range input type

    Form field type that allows the user to select a value using a slider widget.

  3. Search input type

    Search field form input type. Intended to look like the underlying platform's native search field widget (if there is one). Other than its appearance, it's the same as an `<input type="text">`.

  4. Link type "noreferrer"

    Links with `rel="noreferrer"` set do not send the request's "referrer" header. This prevents the destination site from seeing what URL the user came from.

  5. Trusted Types for DOM manipulation

    An API that forces developers to be very explicit about their use of powerful DOM-injection APIs. Can greatly improve security against XSS attacks.
