# property-whitelist
|
||
|
|
|
||
|
|
Specify a whitelist of allowed properties.
|
||
|
|
|
||
|
|
```css
|
||
|
|
a { display: block; }
|
||
|
|
/** ↑
|
||
|
|
* These properties */
|
||
|
|
```
|
||
|
|
|
||
|
|
This rule ignores variables (`$sass`, `@less`, `--custom-property`).
|
||
|
|
|
||
|
|
## Options
|
||
|
|
|
||
|
|
`array|string`: `["array", "of", "unprefixed", "properties" or "regex"]|"property"|"/regex/"`
|
||
|
|
|
||
|
|
If a string is surrounded with `"/"` (e.g. `"/^background/"`), it is interpreted as a regular expression. This allows, for example, easy targeting of shorthands: `/^background/` will match `background`, `background-size`, `background-color`, etc.
|
||
|
|
|
||
|
|
Given:
|
||
|
|
|
||
|
|
```js
|
||
|
|
["display", "animation", "/^background/"]
|
||
|
|
```
|
||
|
|
|
||
|
|
The following patterns are considered warnings:
|
||
|
|
|
||
|
|
```css
|
||
|
|
a { color: pink; }
|
||
|
|
```
|
||
|
|
|
||
|
|
```css
|
||
|
|
a {
|
||
|
|
animation: my-animation 2s;
|
||
|
|
color: pink;
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|

|
|
```css
|
||
|
|
a { borkgrund: orange; }
|
||
|
|
```
|

|
|
|
