css – 不能将angular2-material md-sidenav取为100％的高度

我正在使用带有sidenav的angular2材料制作一个新的angular2应用程序.我不能为了我的生活,使得sidenav的高度是100％.我正在尝试一个菜单来滑出,占据屏幕的整个高度.而且我希望它以相同的方式打开,无论用户滚动的位置.

这是我的模板：

<md-sidenav-layout class="demo-sidenav-layout">
  <md-sidenav #start mode="over">

    <a [routerLink]="['/login']" class="btn btn-priMary">Log in</a>
    <br>
  </md-sidenav>
    <md-toolbar color="priMary">

      <button md-button (click)="start.toggle()">Open Side Drawer</button>
      <span>Spellbook</span>

      <span class="demo-fill-remaining">

      </span>

    </md-toolbar>
  <div class="demo-sidenav-content">

    <router-outlet></router-outlet>
  </div>
</md-sidenav-layout>

这里是我的CSS：

.demo-sidenav-layout {
  //border: 3px solid black;
  min-height:100%;
  md-sidenav {
    padding: 10px;
    BACkground: gainsboro;
    min-height: 100%;
  }
}

.demo-sidenav-content {
  padding: 15px;
  min-height:100%;
}

.demo-toolbar {
  padding: 6px;

  .demo-toolbar-icon {
    padding: 0 14px 0 14px;
  }

  .demo-fill-remaining {
    flex: 1 1 auto;
  }

}

我也有html设置为height：100％,body设置为min-height：100％

<md-sidenav-layout fullscreen>

  <md-sidenav #start mode="over">
    <a [routerLink]="['/login']" class="btn btn-priMary">Log in</a>
    <br>
  </md-sidenav>

  <md-toolbar color="priMary">
    <button md-button (click)="start.toggle()">Open Side Drawer</button>
    <span>Spellbook</span>
    <span class="demo-fill-remaining"></span>
  </md-toolbar>

  <div class="demo-sidenav-content">
    <router-outlet></router-outlet>
  </div>

</md-sidenav-layout>
