media-feature-name-unit-allowed-list

Specify a list of allowed name and unit pairs within media features.

@media (width: 50em) {}
/**     ↑         ↑
 * This media feature name and these units */

Options

object: { "name": ["array", "of", "units"]|"unit" }

If a feature name is surrounded with "/" (e.g. "/height/"), it is interpreted as a regular expression. This allows, for example, easy targeting of shorthands: /height/ will match height, min-height, max-height, etc.

Given:

{
  "width": "em",
  "/height/": ["em", "rem"]
}

The following patterns are considered problems:

@media (width: 50rem) {}

@media (height: 1000px) {}

@media (min-height: 1000px) {}

@media (height <= 1000px) {}

The following patterns are not considered problems:

@media (width: 50em) {}

@media (width <= 50em) {}

@media (height: 50em) {}

@media (min-height: 50rem) {}
