# selector-no-vendor-prefix
Disallow vendor prefixes for selectors.
```css
input::-moz-placeholder {}
/** ↑
* These prefixes */
```
This rule does not blanketly condemn vendor prefixes. Instead, it uses [Autoprefixer's](https://github.com/postcss/autoprefixer) up-to-date data (from [caniuse.com](http://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:
```css
input::-moz-placeholder {}
```
```css
:-webkit-full-screen a {}
```
The following patterns are *not* considered warnings:
```css
input::placeholder {}
```
```css
:full-screen a {}
```
