如何使用 FlexLayout 增加一个组件的高度, Angular 4, Material 设计

How to increase height of one component using FlexLayout, Angular 4, Material Design

我想在两行之间留出一个空隙,如 plunkr 所示,但我也希望中间单元格为蓝色,在顶行,高度不同。

当我改变一个单元格的高度时,它会改变整行。我大一点的是class="two"

我有这个 html:

<md-card class="card-demo">
  <md-card-title>another example</md-card-title>
  <md-card-subtitle>some test work.
  </md-card-subtitle>
  <md-card-content>
    <div fxLayout="column" ng-app="demoApp" layout-fill>
      <div fxLayout="row" fxLayoutGap="20px" flex>
        <div class="one" fxFlex="70"> test1 </div>
        <div class="two" fxFlex="25"> test2 </div>
        <div class="three" fxFlex="25"> test2 </div>
      </div>
      <div fxLayout="column" fxLayoutGap flex>
        <div class="four" fxFlex="150"> test1
          <p>one</p>
          <p>one</p>
        </div>
      </div>
    </div>
  </md-card-content>
</md-card>

还有这个css:

.one {
    background-color: red;
}

.two {
    background-color: blue;
}

.three {
    background-color: green;
}
.four {
    background-color: yellow;
}

您可以添加 fxLayoutAlign 来更改默认的 flex 行为

  <div fxLayout="row" fxLayoutGap="20px" flex fxLayoutAlign="stretch flex-start">
    <div class="one" fxFlex="70"> test1 </div>
    <div class="two" fxFlex="25"> test2 </div>
    <div class="three" fxFlex="25"> test2 </div>
  </div>
