property-no-vendor-prefix

Disallow vendor prefixes for properties.

a { -webkit-transform: scale(1); }
/**  ↑
 * This prefix */

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 violation or not. If you've included a vendor prefixed property that has a standard alternative, one that Autoprefixer could take care of for you, this rule will complain about it. If, however, you use a non-standard vendor-prefixed property, one that Autoprefixer would ignore and could not provide (such as -webkit-touch-callout), this rule will ignore it.
