  3. LCH and Lab color values

  4. CSS revert value

    A CSS keyword value that resets a property's value to the default specified by the browser in its UA stylesheet, as if the webpage had not included any CSS. For example, `display:revert` on a `<div>` would result in `display:block`. This is in contrast to the `initial` value, which is simply defined on a per-property basis, and for `display` would be `inline`.

  5. CSS unset value

  7. CSS currentColor value

    A CSS value that will apply the existing `color` value to other properties like `background-color`, etc.

    Value for `font-family` that represents the default user interface font.

  9. autocomplete attribute: on & off values
