1. CSS Logical Properties

    Logical properties and values provide control of layout through logical, rather than physical, direction and dimension mappings. These properties are `writing-mode` relative equivalents of their corresponding physical properties.

  2. CSS outline properties

    The CSS outline properties draw a border around an element that does not affect layout, making it ideal for highlighting. This covers the `outline` shorthand, as well as `outline-width`, `outline-style`, `outline-color` and `outline-offset`.
