    Feature Targeting

    MDC Feature Targeting provides infrastructure to allow CSS styles to be included or excluded categorically.

    Most of the time, you shouldn't need to depend on mdc-feature-targeting directly. However, understanding it can be useful if you're interested in having more control over when certain types of MDC styles are emitted.

    Installation

    npm install @material/feature-targeting
    

    Basic Usage

    Styles

    Authoring component styles:

    @use "@material/feature-targeting";
    
    @mixin my-component-core-styles($query: feature-targeting.all()) {
      $feat-structure: feature-targeting.create-target($query, structure);
    
      @include feature-targeting.targets($feat-structure) {
        // ...
      }
    }

    Consuming component styles:

    @use "@material/feature-targeting";
    @use "my-component-mixins";
    
    // To include all styles (using the default of mdc-feature-all() defined above):
    @include my-component-core-styles;
    
    // Or, to include a specific subset of styles:
    @include my-component-core-styles(structure);
    @include my-component-core-styles(feature-targeting.any(color, typography));
    // The above two @includes and the following @include would produce equivalent results:
    @include my-component-core-styles(feature-targeting.without(animation));

    Sass Mixins and Functions

    Mixin Description
    targets($feature-targets...) Conditionalizes content to only be emitted if the given feature target(s) is/are queried.
    Function Description
    create-target($feature-query, $targeted-feature) Returns a variable to be passed to targets in order to filter emitted styles.
    all($feature-queries...) Returns a query object which will result in emitting targets blocks that match all of the specified features. Passing no arguments results in all blocks being emitted, which is the most common use case.
    any($feature-queries...) Returns a query object which will result in emitting targets blocks that match any of the specified features. Passing no arguments results in no blocks being emitted.
    without($feature-query) Returns a query object which will result in emitting targets blocks that do not match the specified feature.

    $feature-query and $feature-queries refer to one or more of the values listed below under Supported Features.

    Supported Features

    • structure - All baseline styles that don't fit into any other category
    • animation - Styles responsible for causing animations and transitions to occur
    • color - Color-specific styles which rely on mdc-theme variables
    • typography - Typography-specific styles which rely on mdc-typography
