Specify a blacklist of disallowed properties.

a { text-rendering: optimizeLegibility; }
/** ↑
 * These properties */


array|string: ["array", "of", "unprefixed", "properties" or "regex"]|"property"|"/regex/"

If a string is surrounded with "/" (e.g. "/^background/"), it is interpreted as a regular expression. This allows, for example, easy targeting of shorthands: /^background/ will match background, background-size, background-color, etc.


[ "text-rendering", "animation", "/^background/" ]

The following patterns are considered violations:

a { text-rendering: optimizeLegibility; }
a {
  animation: my-animation 2s;
  color: pink;
a { -webkit-animation: my-animation 2s; }
a { background: pink; }
a { background-size: cover; }

The following patterns are not considered violations:

a { color: pink; }
a { no-background: sure; }
