如何在 AngularDart 中使用 angular 组件在 App 布局中应用迷你变体抽屉

Question

我想在我的项目中使用 Angular Dart 在 angular 组件的应用程序布局中应用迷你变体永久抽屉。我尝试了但没有成功，我该怎么办？

应用css得到以下结果，我怎样才能改变抽屉的大小。

material-drawer {
        max-width: 56px;
    }

app_component.html

<material-drawer persistent #drawer="drawer" [attr.end]="end ? '' : null">
    <material-list *deferredContent>
        <div group class="mat-drawer-spacer"></div>

Answer 1

你们超级亲密我建议做两件事： a) 翻转 app_component.scss 和 layout.scss.css 的顺序。这允许覆盖具有相同的特异性并且仍然适用。 b) 抽屉打开多远由内容的边距宽度处理。所以你的 CSS 应该是这样的：

material-drawer[persistent] + material-content {
  margin-left: 56px;
}

material-drawer {
  max-width: 56px;
}
