# shorthand-property-no-redundant-values
|
||
|
|
|
||
|
|
Disallow redundant values in shorthand properties.
|
||
|
|
|
||
|
|
```css
|
||
|
|
a { margin: 1px 1px 1px 1px; }
|
||
|
|
/** ↑ ↑ ↑
|
||
|
|
* These values */
|
||
|
|
```
|
||
|
|
|
||
|
|
This rule alerts you when you use redundant values in the following shorthand properties:
|
||
|
|
|
||
|
|
- `margin`
|
||
|
|
- `padding`
|
||
|
|
- `border-color`
|
||
|
|
- `border-radius`
|
||
|
|
- `border-style`
|
||
|
|
- `border-width`
|
||
|
|
- `grid-gap`
|
||
|
|
|
||
|
|
The `--fix` option on the [command line](../../../docs/user-guide/cli.md#autofixing-errors) can automatically fix all of the problems reported by this rule.

||
|

|

|
