function-allowed-list

Specify a list of allowed functions.

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

Options

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 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);}
