a { font-size: 10em; }

a { transform: rotate(30deg); }

The following patterns are not considered problems:

a { font-size: 1.2rem; }

a { line-height: 1.2; }

a { height: 100vmin; }

a { animation: animation-name 5s ease; }

Optional secondary options

ignoreProperties: { "unit": ["property", "/regex/", /regex/]|"property"|"/regex/"|/regex/ }

Ignore units in the values of declarations with the specified properties.

For example, with ["px", "vmin"].

Given:

  "vmin": "width"
}

The following patterns are not considered problems:

a { font-size: 13px; }

a { border-bottom-width: 6px; }

a { width: 100vmin; }

The following patterns are considered problems:

a { line-height: 12px; }

a { -moz-border-radius-topright: 40px; }

a { height: 100vmin; }

ignoreMediaFeatureNames: { "unit": ["property", "/regex/", /regex/]|"property"|"/regex/"|/regex/ }

For example, with ["px", "dpi"].

Given:

  "dpi": "resolution"
}

The following patterns are not considered problems:

@media (min-width: 960px) {}

@media (max-height: 280px) {}

@media not (resolution: 300dpi) {}

The following patterns are considered problems:

@media screen and (max-device-width: 500px) {}

@media all and (min-width: 500px) and (max-width: 200px) {}

@media print and (max-resolution: 100dpi) {}

ignoreFunctions: ["function", "/regex/", /regex/]|"function"|"/regex/"|/regex/

Ignore units that are inside of the specified functions.

For example, with ["px"].

Given:

["calc", "/^translate/"]

The following patterns are not considered problems:

a { margin: calc(50% - 100px) }

a { transform: translateX(100px) }
