Pattern: Unexpected vendor-prefix selector
Issue: -
This rule 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 selector 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 selector, one that Autoprefixer would ignore and could not provide, this rule will ignore it.
The following patterns are considered violations:
input::-moz-placeholder {}
/** ↑
* These prefixes */:-webkit-full-screen a {}The following patterns are not considered violations:
input::placeholder {}:full-screen a {}
