stylelint-config-standard

The standard shareable config for stylelint.

Extends 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, Google’s CSS Style Guide, Airbnb’s Styleguide, and @mdo’s Code Guide.

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.

Example

@import url(x.css);
@import url(y.css);

/**
 * Multi-line comment
 */

.selector-1,
.selector-2,
.selector-3[type="text"] {
  background: linear-gradient(#fff, rgba(0, 0, 0, 0.8));
  box-sizing: border-box;
  display: block;
  color: #333;
}

.selector-a,
.selector-b:not(:first-child) {
  padding: 10px !important;
  top: calc(calc(1em * 2) / 3);
}

.selector-x { width: 10%; }
.selector-y { width: 20%; }
.selector-z { width: 30%; }

/* Single-line comment */

@media (min-width >= 60em) {
  .selector {
    /* Flush to parent comment */
    transform: translate(1, 1) scale(3);
  }
}

@media (orientation: portrait), projection and (color) {
  .selector-i + .selector-ii {
    background: color(rgb(0, 0, 0) lightness(50%));
    font-family: helvetica, "arial black", sans-serif;
  }
}

/* Flush single line comment */
@media
  screen and (min-resolution: 192dpi),
  screen and (min-resolution: 2dppx) {
  .selector {
    background-image:
      repeating-linear-gradient(
        -45deg,
        transparent,
        #fff 25px,
        rgba(255, 255, 255, 1) 50px
      );
    margin: 10px;
    margin-bottom: 5px;
    box-shadow:
      0 1px 1px #000,
      0 1px 0 #fff,
      2px 2px 1px 1px #ccc inset;
    height: 10rem;
  }

  /* Flush nested single line comment */
  .selector::after {
    content: '→';
    background-image: url(x.svg);
  }
}

Note: the config is tested against this example, as such the example contains plenty of CSS syntax, formatting and features.

Installation

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:

{
  "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.

{
  "extends": "/absolute/path/to/stylelint-config-standard"
}

Since stylelint 9.7.0, you can simply use the globally installed configuration name instead of the absolute path:

{
  "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:

{
  "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:
If you use autoprefixer you’ll want to disallow vendor prefixes using:
Control specificity using:
Specify acceptable selector types, units, properties, functions and words in comments using:
Specify acceptable naming patterns using:
Specify a notation when there are one or more valid representations using:
- font-weight-notation
Specify what types of URLs are allowed using:
- function-url-no-scheme-relative
Specify a maximum line length using:
- max-line-length

Using the config with SugarSS syntax

The config is broadly compatible with SugarSS syntax. You will need to turn off the rules that check braces and semicolons, as so:

{
  "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
  }
}
