在材质组件中将组件特定样式设置为生成的 HTML

Question

我已向组件添加了一个无线电组：

<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>

这会在站点中呈现以下 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>

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

我尝试过类似的方法：

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

和

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

但是选择器错了。

在不全局设置样式的情况下访问这些节点和设置样式的正确方法是什么？是否有可能或者是全局样式唯一的方法？

愚蠢的错误。我使用的是::ngdeep 而不是::ng-deep。
