Angular 2 Material中的粘性页脚

我一直在搜索和搜索大约3个小时,因为我不想要问,但我怎么能在底部保留一个“页脚”变量,而不是像固定在底部,所以如果我的内容是非常小,它不会只是坐在页面中间,但如果我有很多信息,它将不会锁定在页面的底部,并在滚动时坐在那里数据

我尝试了几种方法,包括：

大多数与此相关的问题我已经测试过,或者似乎没有工作或者根本没有工作.

继承我目前的代码：

<div class="content">
  <app-navbar></app-navbar>
  <app-footer></app-footer>
</div>

和< app-content>< / app-content>在导航栏内,因为导航栏控制整页sidenav.

整个app-navbar看起来像这样：

<mat-sidenav-container fullscreen>

  <mat-sidenav mode="push" #sidenav>
    <div fxLayout="column">
      <mat-toolbar fxLayoutAlign="center center" color="primary">
        <button mat-icon-button routerLink="/home" (click)="sidenav.close()">
          <mat-icon>keyboard_backspace</mat-icon>
        </button>
      </mat-toolbar>
      <button mat-button routerLink="/dashboard" (click)="sidenav.close()" >Information</button>
      <button mat-button routerLink="/second" (click)="sidenav.close()" >Web tools</button>
    </div>
  </mat-sidenav>
  <mat-toolbar color="primary" class="fixed-navbar mat-elevation-z10">
    <button mat-icon-button (click)="sidenav.open()" fxHide="false" fxHide.gt-xs>
      <mat-icon>menu</mat-icon>
    </button>

    <div fxLayout="row">
      <button fxLayout="flex-shrink: 0;" mat-button class="title" style="font-size: 25px;">{{this.title}}</button>
      <button fxShow="false" fxShow.gt-xs mat-button routerLink="/dashboard" [matMenuTriggerFor]="infoMenu">Information</button>
      <button fxShow="false" fxShow.gt-xs mat-button routerLink="/second" [matMenuTriggerFor]="toolsMenu">Web tools</button>
    </div>
    <!-- fxFlex will fill the empty space and push the following items to the right -->
    <div fxFlex></div>
    <button mat-icon-button>
      <mat-icon>face</mat-icon>
    </button>
  </mat-toolbar>
  <app-container></app-container>

</mat-sidenav-container>

页脚只是一个超级基本组件,如下所示：

<mat-toolbar>
  <div class="container">
    <span>this is a toolbar</span>
  </div>
</mat-toolbar>

到目前为止,只有样式的应用是这样的：

@import url('https://fonts.googleapis.com/css?family=Comfortaa');
.title {
  font-family: "Comfortaa";
}
html,body {
  height: 100%;
  margin: 0;
}
.content {
  min-height: 100%;
}

这是在全局style.css文件中.

<mat-sidenav-container class="all-wrap" fullscreen>
  <mat-sidenav #sidenav>
    <mat-list>
      <mat-list-item [routerLink]="['/']"> Foo</mat-list-item>
      <mat-list-item [routerLink]="['/bar']"> Bar</mat-list-item>
    </mat-list>
  </mat-sidenav>

  <div class="page-wrap">
    <header role="banner">
      <mat-toolbar color="primary">
        <button
          type="button"
          mat-icon-button
          (click)="sidenav.open()"
          title="Open sidenav">
          <mat-icon>menu</mat-icon>
        </button>
        Your Toolbar
      </mat-toolbar>
    </header>
    <main class="content">
      <router-outlet></router-outlet>
    </main>
    <footer>
      Your sticky footer with a variable height.
    </footer>
  </div>
</mat-sidenav-container>

/*
 * Actual Sticky Footer Styles
 */
.all-wrap {
  min-height: 100vh;
}

.page-wrap {
  display: flex;
  flex-direction: column;
  min-height: 100vh;
}

.content {
  flex: 1;
}


/*
 * Make the Component injected by Router Outlet full height:
 */
main {
  display: flex;
  flex-direction: column;
  > *:not(router-outlet) {
    flex: 1;
    display: block;
  }
}
