media-feature-name-value-whitelist

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

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

This rule ignores media features within range and boolean context.

Options

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

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

If a name or value is surrounded with / (e.g. "/width$/"), it is interpreted as a regular expression. For example, /width$/ will match max-width and min-width.

Given:

{
  "min-width": ["768px", "1024px"],
  "/resolution/": ["/dpcm$/"]
}

The following patterns are considered violations:

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

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

The following patterns are not considered violations:

@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) {}
