# stylelint-config-standard

[](https://www.npmjs.org/package/stylelint-config-standard) [](https://github.com/stylelint/stylelint-config-standard/actions)
|
|
|
|
> The standard shareable config for Stylelint.
|
|
|
|
It extends [`stylelint-config-recommended`](https://github.com/stylelint/stylelint-config-recommended) and turns on additional rules to enforce modern conventions found in the [CSS specifications](https://www.w3.org/Style/CSS/current-work).
|
|
|
|
To see the rules that this config uses, please read the [config itself](./index.js).
|
|
|
|
## Example
|
|
|
|
```css
|
|
@import url("foo.css");
|
|
@import url("bar.css");
|
|
|
|
@custom-media --foo (min-width: 30em);
|
|
|
|
/**
|
|
* Multi-line comment
|
|
*/
|
|
|
|
:root {
|
|
--brand-red: hsl(5deg 10% 40%);
|
|
}
|
|
|
|
/* Single-line comment */
|
|
|
|
.class-foo:not(a, div) {
|
|
margin: 0;
|
|
top: calc(100% - 2rem);
|
|
}
|
|
|
|
/* Flush single line comment */
|
|
@media (width >= 60em) {
|
|
#id-bar {
|
|
/* Flush to parent comment */
|
|
--offset: 0px;
|
|
|
|
color: #fff;
|
|
font-family: Helvetica, "Arial Black", sans-serif;
|
|
left: calc(var(--offset) + 50%);
|
|
}
|
|
|
|
/* Flush nested single line comment */
|
|
a::after {
|
|
display: block;
|
|
content: "→";
|
|
background-image: url("x.svg");
|
|
}
|
|
}
|
|
|
|
@keyframes fade-in {
|
|
from {
|
|
opacity: 0;
|
|
}
|
|
|
|
to {
|
|
opacity: 1;
|
|
}
|
|
}
|
|
```
|
|
|
|
_Note: the config is tested against this example, as such the example contains plenty of CSS syntax and features._
|
|
|
|
## Installation
|
|
|
|
```bash
|
|
npm install stylelint-config-standard --save-dev
|
|
```
|
|
|
|
## Usage
|
|
|
|
Set your Stylelint config to:
|
|
|
|
```json
|
|
{
|
|
"extends": "stylelint-config-standard"
|
|
}
|
|
```
|
|
|
|
### Extending the config
|
|
|
|
Add a `"rules"` key to your config, then add your overrides and additions there.
|
|
|
|
You can turn off rules by setting its value to `null`. For example:
|
|
|
|
```json
|
|
{
|
|
"extends": "stylelint-config-standard",
|
|
"rules": {
|
|
"selector-class-pattern": null
|
|
}
|
|
}
|
|
```
|
|
|
|
Or lower the severity of a rule to a warning using the `severity` secondary option. For example:
|
|
|
|
```json
|
|
{
|
|
"extends": "stylelint-config-standard",
|
|
"rules": {
|
|
"property-no-vendor-prefix": [
|
|
true,
|
|
{
|
|
"severity": "warning"
|
|
}
|
|
]
|
|
}
|
|
}
|
|
```
|
|
|
|
Or to add a rule, For example, the `unit-allowed-list` one:
|
|
|
|
```json
|
|
{
|
|
"extends": "stylelint-config-standard",
|
|
"rules": {
|
|
"unit-allowed-list": ["em", "rem", "s"]
|
|
}
|
|
}
|
|
```
|
|
|
|
We recommend adding more of [Stylelint's rules](https://stylelint.io/user-guide/rules/) to your config as these rules need to be configured to suit your specific needs.
