# 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.
|
||
|
|
|
||
|
|
Extends [`stylelint-config-recommended`](https://github.com/stylelint/stylelint-config-recommended).
|
||
|
|
|
||
|
|
Turns on additional rules to enforce the common stylistic conventions found within a handful of CSS styleguides, including: [The Idiomatic CSS Principles](https://github.com/necolas/idiomatic-css),
|
||
|
|
[Google's CSS Style Guide](https://google.github.io/styleguide/htmlcssguide.html#CSS_Formatting_Rules), [Airbnb's Styleguide](https://github.com/airbnb/css#css), and [@mdo's Code Guide](https://codeguide.co/#css).
|
||
|
|
|
||
|
|
It favours flexibility over strictness for things like multi-line lists and single-line rulesets, and tries to avoid potentially divisive rules.
|
||
|
|
|
||
|
|
Use it as is or as a foundation for your own config.
|
||
|
|
|
||
|
|
To see the rules that this config uses, please read the [config itself](./index.js).

|

|
|
|
||
|
|
_Note: the config is tested against this example, as such the example contains plenty of CSS syntax, formatting and features._
|
||
|
|
|
||
|
|
## Installation
|
||
|
|
|
||
|
|
```bash
|
||
|
|
npm install stylelint-config-standard --save-dev
|
||
|
|
```
|
||
|
|
|
||
|
|
## Usage
|
||
|
|
|
||
|
|
If you've installed `stylelint-config-standard` locally within your project, just set your `stylelint` config to:
|
||
|
|
|
||
|
|
```json
|
||
|
|
{
|
||
|
|
"extends": "stylelint-config-standard"
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
If you've globally installed `stylelint-config-standard` using the `-g` flag, then you'll need to use the absolute path to `stylelint-config-standard` in your config e.g.
|
||
|
|
|
||
|
|
```json
|
||
|
|
{
|
||
|
|
"extends": "/absolute/path/to/stylelint-config-standard"
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
Since [stylelint 9.7.0](https://github.com/stylelint/stylelint/blob/9.7.0/CHANGELOG.md#970), you can simply use the globally installed configuration name instead of the absolute path:
|
||
|
|
|
||
|
|
```json
|
||
|
|
{
|
||
|
|
"extends": "stylelint-config-standard"
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
### Extending the config
|
||
|
|
|
||
|
|
Simply add a `"rules"` key to your config, then add your overrides and additions there.
|
||
|
|
|
||
|
|
For example, to change the `at-rule-no-unknown` rule to use its `ignoreAtRules` option, change the `indentation` to tabs, turn off the `number-leading-zero` rule,and add the `unit-allowed-list` rule:
|
||
|
|
|
||
|
|
```json
|
||
|
|
{
|
||
|
|
"extends": "stylelint-config-standard",
|
||
|
|
"rules": {
|
||
|
|
"at-rule-no-unknown": [
|
||
|
|
true,
|
||
|
|
{
|
||
|
|
"ignoreAtRules": ["extends", "ignores"]
|
||
|
|
}
|
||
|
|
],
|
||
|
|
"indentation": "tab",
|
||
|
|
"number-leading-zero": null,
|
||
|
|
"unit-allowed-list": ["em", "rem", "s"]
|
||
|
|
}
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
#### Suggested additions
|
||
|
|
|
||
|
|
`stylelint-config-standard` is a great foundation for your own config. You can extend it to create a tailored and much stricter config:
|
||
|
|
|
||
|
|
- Specify what quotes must be used using:
|
||
|
|
- [`font-family-name-quotes`](https://github.com/stylelint/stylelint/blob/master/lib/rules/font-family-name-quotes/README.md)
|
||
|
|

|
||
|
|
- [`string-quotes`](https://github.com/stylelint/stylelint/blob/master/lib/rules/string-quotes/README.md)
|
||
|
|
- If you use [`autoprefixer`](https://github.com/postcss/autoprefixer) you'll want to disallow vendor prefixes using:
|
||
|
|

### Using the config with SugarSS syntax
|
||
|
|
|
||
|
|
The config is broadly compatible with [SugarSS](https://github.com/postcss/sugarss) syntax. You _will_ need to turn off the rules that check braces and semicolons, as so:
|
||
|
|
|
||
|
|
```json
|
||
|
|
{
|
||
|
|
"extends": "stylelint-config-standard",
|
||
|
|
"rules": {
|
||
|
|
"block-closing-brace-empty-line-before": null,
|
||
|
|
"block-closing-brace-newline-after": null,
|
||
|
|
"block-closing-brace-newline-before": null,
|
||
|
|
"block-closing-brace-space-before": null,
|
||
|
|
"block-opening-brace-newline-after": null,
|
||
|
|
"block-opening-brace-space-after": null,
|
||
|
|
"block-opening-brace-space-before": null,
|
||
|
|
"declaration-block-semicolon-newline-after": null,
|
||
|
|
"declaration-block-semicolon-space-after": null,
|
||
|
|
"declaration-block-semicolon-space-before": null,
|
||
|
|
"declaration-block-trailing-semicolon": null
|
||
|
|
}
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
