selector-no-vendor-prefix

Disallow vendor prefixes for selectors.

input::-moz-placeholder {}
/**     ↑
 * These prefixes */

This rule does not blanketly condemn vendor prefixes. Instead, it uses Autoprefixer's up-to-date data (from caniuse.com) to know whether a vendor prefix should cause a warning or not. If you've included a vendor prefixed selector that has a standard alternative, one that Autoprefixer could take care of for you, this rule will warn about it. If, however, you use a non-standard vendor-prefixed selector, one that Autoprefixer would ignore and could not provide, this rule will ignore it.

Options

true

The following patterns are considered warnings:

input::-moz-placeholder {}
