/** ### forSize
* This mixin allows us to apply some rules selectively based on the screen
* size. There are three primary sizes: `small`, `medium`, and `large`, which
* are mutually exclusive. Additionally there are two additional sizes:
* `notSmall` and `ultraLarge`. `notSmall`, as the name implies matches any
* value which is not the small screen size, so it overlaps with medium,
* large, and ultraLarge. `ultraLarge` defines a wider minimum screen size
* than large, but neither large nor ultraLarge specify maximum widths,
* so ultraLarge is a strict subset of large. A screen large enough to match
* ultraLarge will also match large (compare with medium and large: matching
* medium means it will not match large, and vice versa). */
