value-no-vendor-prefix

Disallow vendor prefixes for values.

a { display: -webkit-flex; }
/** ↑
* This prefix */

This rule does not fix vendor-prefixed values that weren't handled by Autoprefixer version 10.2.5. Exceptions may be added on a case by case basis.

The fix option can automatically fix all of the problems reported by this rule. However, it will not remove duplicate values produced when the prefixes are removed. You can use Autoprefixer itself, with the add option off and the remove option on, in these situations.

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

Options

true

The following patterns are considered problems:

a { display: -webkit-flex; }
a { max-width: -moz-max-content; }
a { background: -webkit-linear-gradient(bottom, #000, #fff); }

The following patterns are not considered problems:

a { display: flex; }
a { max-width: max-content; }
a { background: linear-gradient(bottom, #000, #fff); }

Optional secondary options

ignoreValues: ["/regex/", /regex/, "string"]

Given:

["grab", "max-content", "/^-moz-all$/"]

The following patterns are not considered problems:

a { cursor: -webkit-grab; }
a { max-width: -moz-max-content; }
a { -moz-user-select: -moz-all; }
注意

An exact match comparison will be performed for non-regex strings in the next major version. If you want to keep the legacy behavior, please consider using a regex instead. E.g. [/^(-webkit-|-moz-)?max-content$/].
