Usage

Set your Stylelint config to:

{
  "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:

{
  "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:

{
  "extends": "stylelint-config-standard",
  "rules": {
    "property-no-vendor-prefix": [
      true,
      {
        "severity": "warning"
      }
    ]
  }
}

Or to add a rule, For example, the unit-allowed-list one:

{
  "extends": "stylelint-config-standard",
  "rules": {
    "unit-allowed-list": ["em", "rem", "s"]
  }
}

We recommend adding more of Stylelint's rules to your config as these rules need to be configured to suit your specific needs.
