# property-no-vendor-prefix
|
|||
|
|
|
|||
|
|
Disallow vendor prefixes for properties.
|
|||
|
|
|
|||
|
|
```css
|
|||
|
|
a { -webkit-transform: scale(1); }
|
|||
|
|
/** ↑
|
|||
|
|
* 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 property 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 property, one that Autoprefixer would ignore and could not provide (such as `-webkit-touch-callout`), this rule will ignore it.

## Options

### `true`

The following patterns are considered warnings:
|
|||
|
|
|
|||
|
|
```css
|
|||
|
|
a { -webkit-transform: scale(1); }
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
```css
|
|||
|
|
a { -moz-columns: 2; }
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
The following patterns are *not* considered warnings:
|
|||
|
|
|
|||
|
|
```css
|
|||
|
|
a { transform: scale(1); }
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
```css
|
|||
|
|
a {
|
|||
|
|
columns: 2; }
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
```css
|
|||
|
|
a { -webkit-touch-callout: none; }
|
|||
|
|
```
