使弹性行拉伸到单元格中内容的高度 - 内容从容器DIV中渗出

Question

我通常会问关于Angular的问题，但今天我对CSS和FlexBox有疑问。在我的应用程序中，我显示一些关于界面，用户名，公司名称和部门名称的信息，如果信息很长（如一个有很多字符的长名称）我希望文本在其单元格中包装，文本显示的行成长以适应文本。文本不应该渗入下面的行。

我的HTML看起来像......

<div class="assignment">
  <!-- Here we want to colums, one to contain the rows of info
      The other to contain a single button -->
  <div class="assignment__details">
    <div class="assignment__row">
      <div class="assignment__row__title">User</div>
      <div class="assignment__row__value">
        Oh this is a long user name
      </div>
    </div>
    <div class="assignment__row">
      <div class="assignment__row__title">Company:</div>
      <div class="assignment__row__value">
        Oh this is a long company name
      </div>
    </div>
    <div class="assignment__row">
      <div class="assignment__row__title">Department:</div>
      <div class="assignment__row__value" >
        This is Such a long Department Name
      </div>
    </div>
  </div>
  <!-- here is the col with the button -->
  <div class="assignment__controls">
    <button mat-icon-button (click)="doSomething()">
      <mat-icon>edit</mat-icon>
    </button>
  </div>
</div>

这是我的CSS（少用BEM写的）

.assignment {
  display: flex;
  background-color: #C0C0C0;
  padding: 10px;
  width: 300px; // just for demo puropses

  &__details {
    flex: 1 1 80%;
  }

  &__controls {
    display: flex;
    flex: 1 1 20%;
    justify-content: flex-end;
    align-items: center;
  }

  &__row {
    display: flex;
    height: 21px;

    &__title {
      flex: 1 0 50%;
    }

    &__value {
      flex: 1 0 50%;
    }
  }
}

这是一个JS Bin https://jsbin.com/juguvovelo/edit?html,css,output

正如你所看到的那样，文本会流入下面的行并从容器中流出！正如这个屏幕截图所示！我设置flex-growbut的.assignment__row似乎没有得到我想要的效果？

如果有人能帮我解决这个问题，我将非常感激。也许这是我的HTML结构的问题？

Answer 1

你需要从.assignment__row移除高度。这是一个JSBin link。

Answer 2

删除height的assignment__row

.assignment {
	 display: flex;
	 background-color: #c0c0c0;
	 padding: 10px;
	 width: 300px;
}
 .assignment__details {
	 flex: 1 1 80%;
}
 .assignment__controls {
	 display: flex;
	 flex: 1 1 20%;
	 justify-content: flex-end;
	 align-items: center;
}
 .assignment__row {
	 display: flex;
}
 .assignment__row__title {
	 flex: 1 0 50%;
}
 .assignment__row__value {
	 flex: 1 0 50%;
}
 

<div class="assignment">
  <!-- Here we want to colums, one to contain the rows of info
      The other to contain a single button -->
  <div class="assignment__details">
    <div class="assignment__row">
      <div class="assignment__row__title">User</div>
      <div class="assignment__row__value">
        Oh this is a long user name
      </div>
    </div>
    <div class="assignment__row">
      <div class="assignment__row__title">Company:</div>
      <div class="assignment__row__value">
        Oh this is a long company name
      </div>
    </div>
    <div class="assignment__row">
      <div class="assignment__row__title">Department:</div>
      <div class="assignment__row__value" >
        This is Such a long Department Name
      </div>
    </div>
  </div>
  <!-- here is the col with the button -->
  <div class="assignment__controls">
    <button mat-icon-button (click)="doSomething()">
      <mat-icon>edit</mat-icon>
    </button>
  </div>
</div>
