PostCSS Auto Reset

PostCSS plugin for automatic conditional rules reset. Useful for creation of bullet-proof styles isolation in your extension. Can be used in combination with postcss-initial.

.block {
  padding: 1em;
}

.block__element {
  margin: 1em;
}

.block--modifier {
  border: 1em;
}

.block { /* reseted */
  all: initial;
  padding: 1em;
}

.block__element { /* reseted */
  all: initial;
  margin: 1em;
}

.block--modifier { /* ignored, we don`t need to reset BEM modifiers  */
  border: 1em;
}

Options

reset

Set of properties that we use to reset rules.
Takes string or object.
Possible values:

• 'initial' - all: initial;
• 'sizes' - reset size properties.

Use object to create your own reset.

Example

postcss([ require('postcss-autoreset')({
    reset: {
      'margin': '0',
      'padding': '0',
      'border-radius': '0'
    }
  })])

rulesMatcher

Rules filter function.
Takes string or function.
Possible values:

• 'bem' - reset all BEM blocks and element, ignore modifiers. (naming: .block__element-modifier);
• 'suit' - reset all SUIT CSS components and parts, ignore modifiers and states.

You can define custom rules filter to fit your styles naming.

Example

postcss([ require('postcss-autoreset')({
  rulesMatcher: (rule)=> rule.selector.match(/regexp/)
  })])

Usage

postcss([ require('postcss-autoreset')])

See PostCSS docs for examples for your environment.
