function-allowed-list

Specify a list of allowed functions.

a { transform: scale(1); }
/**            ↑
 * This function */

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

Options

array|string|regex: ["array", "of", "unprefixed", /functions/, "/regex/"]|"function"|"/regex/"|/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 problems:

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 problems:

a { background: red; }

a { transform: scale(1); }

a {
  color: rgba(0, 0, 0, 0.5);
}

a {
  background:
    red,
    -moz-linear-gradient(45deg, blue, red);
}
