Specify a whitelist of allowed functions.
a { transform: scale(1); } /** ↑ * This function */
array|string
: ["array", "of", "unprefixed", /functions/ or "regex"]|"function"|"/regex/"
If a string is surrounded with "/"
(e.g. "/^rgb/"
), it is interpreted as a regular expression.
Given:
["scale", "rgba", "linear-gradient"]
The following patterns are considered violations:
a { transform: rotate(1); }
a { color: hsla(170, 50%, 45%, 1) }
a { background: red, -webkit-radial-gradient(red, green, blue); }
The following patterns are not considered violations:
a { background: red; }
a { transform: scale(1); }
a { color: rgba(0, 0, 0, 0.5); }
a { background: red, -moz-linear-gradient(45deg, blue, red); }
