css - Mat-Stepper - 将特定步骤更改为点

Question

我看过这篇关于如何删除标题的帖子 Remove the Material Stepper header

但我想要在特定步骤上的所有内容是在显示数字的跨度上不显示任何内容。

隐藏步进器的内部部分:

<span class="mat-step-icon-content ng-star-inserted">1</span>

我尝试使用 id 和 .span:after 或者只是 .span 不显示，但没有成功..

#importer > .span{
  display:none;
}

这个有效，但我不希望它一起消失..只是数字和特定步骤..

::ng-deep #importer > .mat-horizontal-stepper-header-container {
  display: none !important;
}

问题:

1) 步进器的响应度；

2) 正确的样式只有在经过特定的步进步骤之后

Answer 1

您将无法通过使用类来执行此操作，因此它不能是动态的。如果这不是问题，那么我建议使用 SASS mixin 来创建每个标题项所需的样式。示例:

Demo

@mixin hide-option($index, $label: '') {
  mat-step-header:nth-of-type(#{$index}) {
    .mat-step-icon-not-touched span,
    .mat-step-icon span,
    .mat-step-icon-not-touched .mat-icon,
    .mat-step-icon .mat-icon {
      display: none;
    }

    @if ($label == '') {
      .mat-step-icon {
        height: 5px;
        width: 5px;
      }
    }

    .mat-step-icon-not-touched:after,
    .mat-step-icon:after {
      content: $label;
      position: absolute;
      left: 8px;
      top: 3px;
    }
  }
}

:host /deep/ {

  mat-step-header .mat-step-label {
      overflow: visible;
  }

  @include hide-option(1, '1');
  @include hide-option(2);
  @include hide-option(3);
  @include hide-option(4);
  @include hide-option(5, '2');
  @include hide-option(6);
  @include hide-option(7);
  @include hide-option(8);
  @include hide-option(9, '3');
  @include hide-option(10, '4');
  @include hide-option(11);
  @include hide-option(12, '5');
  @include hide-option(13, '6');
}
