将特定于组件的样式设置为材料组件中生成的HTML

Question

我已将无线电组添加到组件：

<div class="auction-filter-wrapper">
  <mat-radio-group class="auction-filter" (change)="onChange($event)">
    <mat-radio-button class="auction-filter-button" value="0">Both</mat-radio-button>
    <mat-radio-button class="auction-filter-button" value="Bid">Bid</mat-radio-button>
    <mat-radio-button class="auction-filter-button" value="BuyNow">Buy Now</mat-radio-button>
  </mat-radio-group>
</div>

这将在站点中呈现以下HTML：

<div _ngcontent-c32="" class="auction-filter-wrapper">
  <mat-radio-group _ngcontent-c32="" class="auction-filter mat-radio-group" role="radiogroup">
    <mat-radio-button _ngcontent-c32="" class="auction-filter-button mat-radio-button mat-accent" value="0"
      ng-reflect-value="0" id="mat-radio-2"><label class="mat-radio-label" for="mat-radio-2-input">
        <div class="mat-radio-container">
          <div class="mat-radio-outer-circle"></div>
          <div class="mat-radio-inner-circle"></div>
          <div class="mat-radio-ripple mat-ripple" mat-ripple="" ng-reflect-centered="true" ng-reflect-radius="23"
            ng-reflect-animation="[object Object]" ng-reflect-disabled="false" ng-reflect-trigger="[object HTMLLabelElement]"></div>
        </div><input class="mat-radio-input cdk-visually-hidden" type="radio" id="mat-radio-2-input" tabindex="0" name="mat-radio-group-0">
        <div class="mat-radio-label-content"><span style="display:none">&nbsp;</span>Both</div>
      </label></mat-radio-button>
    <mat-radio-button _ngcontent-c32="" class="auction-filter-button mat-radio-button mat-accent" value="Bid"
      ng-reflect-value="Bid" id="mat-radio-3"><label class="mat-radio-label" for="mat-radio-3-input">
        <div class="mat-radio-container">
          <div class="mat-radio-outer-circle"></div>
          <div class="mat-radio-inner-circle"></div>
          <div class="mat-radio-ripple mat-ripple" mat-ripple="" ng-reflect-centered="true" ng-reflect-radius="23"
            ng-reflect-animation="[object Object]" ng-reflect-disabled="false" ng-reflect-trigger="[object HTMLLabelElement]"></div>
        </div><input class="mat-radio-input cdk-visually-hidden" type="radio" id="mat-radio-3-input" tabindex="0" name="mat-radio-group-0">
        <div class="mat-radio-label-content"><span style="display:none">&nbsp;</span>Bid</div>
      </label></mat-radio-button>
    <mat-radio-button _ngcontent-c32="" class="auction-filter-button mat-radio-button mat-accent" value="BuyNow"
      ng-reflect-value="BuyNow" id="mat-radio-4"><label class="mat-radio-label" for="mat-radio-4-input">
        <div class="mat-radio-container">
          <div class="mat-radio-outer-circle"></div>
          <div class="mat-radio-inner-circle"></div>
          <div class="mat-radio-ripple mat-ripple" mat-ripple="" ng-reflect-centered="true" ng-reflect-radius="23"
            ng-reflect-animation="[object Object]" ng-reflect-disabled="false" ng-reflect-trigger="[object HTMLLabelElement]"></div>
        </div><input class="mat-radio-input cdk-visually-hidden" type="radio" id="mat-radio-4-input" tabindex="0" name="mat-radio-group-0">
        <div class="mat-radio-label-content"><span style="display:none">&nbsp;</span>Buy Now</div>
      </label></mat-radio-button>
  </mat-radio-group>
</div>

如何为诸如<label class="mat-radio-label" for="mat-radio-2-input">元素指定组件范围样式？

我已经尝试过类似的事情：

:host {
    .auction-filter-button {
        ::ngdeep {
            label {
                padding-left: 0 !important;
            }
        }
    }
}

和

:host {
    .auction-filter-button {
        label {
            padding-left: 0 !important;
        }
    }
}

但是选择器是错误的。

在不全局设置样式的情况下，访问这些节点并设置样式的正确方法是什么？ 是否有可能或者只有全球风格才能做到？

Answer 1

愚蠢的错误。 我使用::ngdeep而不是::ng-deep 。
