media-feature-name-value-allowed-list

Specify a list of allowed media feature name and value pairs.

@media screen and (min-width: 768px) {}
/**                ↑          ↑
 *    These features and values */

The message secondary option can accept the arguments of this rule.

Options

Object<string, Array<string>>

{ "unprefixed-media-feature-name": ["array", "of", "values", "/regex/"] }

You can specify a regex for a media feature name, such as { "/width$/": [] }.

If a media feature name is found in the object, only its allowed-listed values are allowed. If the media feature name is not included in the object, anything goes.

Given:

{
  "media-feature-name-value-allowed-list": {
    "min-width": ["768px", "1024px"],
    "/resolution/": ["/dpcm$/"]
  }
}

The following patterns are considered problems:

@media screen and (min-width: 1000px) {}

@media screen and (min-resolution: 2dpi) {}

@media screen and (min-width > 1000px) {}

The following patterns are not considered problems:

@media screen and (min-width: 768px) {}

@media screen and (min-width: 1024px) {}

@media screen and (orientation: portrait) {}

@media screen and (min-resolution: 2dpcm) {}

@media screen and (resolution: 10dpcm) {}

@media screen and (768px < min-width) {}
