如何在Bootstrap中自动调整行高? [英] How to automatically adjust row height in Bootstrap?

问题描述

我正在学习Bootstrap，并且试图弄清楚在这种情况下如何自动调整行高:

I'm learning Bootstrap and I'm trying to figure out how to automatically adjust a rows height given this conditions:

• 容器流体
中有3行
• 第1行必须调整为其内容的高度
• 第3行必须调整为其内容的高度，并位于视口的底部
• 第2行应将其高度调整为第1行和第3行之间的空间，以填充容器流体

• There are 3 rows within a container-fluid
• row1 must adjust to the height of its content
• row3 must adjust to the height of its content and be at the bottom of the viewport
• row2 should adjust its height to the space between row1 and row3 to fill the container-fluid

html, body, .container-fluid {
  height: 100%;
  background: lightyellow;
}

.col {
  border: solid 1px #6c757d;
}

.content-1 {
  height: 50px;
  background-color: lightcoral;
}

.content-2 {
  height: 200px;
    background-color: lightgreen;
}

.content-3 {
  height: 25px;
  background-color: lightblue;
}

<div class="container-fluid">
  <div class="row">
    <div class="col">
      <div class="content-1">
      ROW 1 -> Height of its content
      </div>
    </div>
  </div>
  <div class="row">
    <div class="col">
      <div class="content-2">
      ROW 2 -> Height between row1 and row3 automatically adjusted
      </div>
    </div>
  </div>
  <div class="row">
    <div class="col">
      <div class="content-3">
      ROW 3 -> Height of its content
      </div>
    </div>
  </div>
</div>

推荐答案

您正在寻找flexbox实用程序类. d-flex用于display:flex，flex-grow-1将使第二个子div填充剩余的高度.要使用垂直布局，请使用flex-column.

You're looking for the flexbox utility classes. d-flex is for display:flex, and flex-grow-1 will make the 2nd child div fill the remaining height. Use flex-column as you want a vertical layout.

<div class="container-fluid d-flex flex-column">
  <div class="row">
    <div class="col">
      <div class="content-1">
      ROW 1 -> Height of its content
      </div>
    </div>
  </div>
  <div class="row flex-fill">
    <div class="col d-flex flex-column">
      <div class="content-2 h-100">
      ROW 2 -> Height between row1 and row3 automatically adjusted
      </div>
    </div>
  </div>
  <div class="row">
    <div class="col">
      <div class="content-3">
      ROW 3 -> Height of its content
      </div>
    </div>
  </div>
</div>

注意:自定义CSS中设置的固定高度已被删除，以使页眉/页脚可以作为其内容的高度，而内容行则可以填充剩余的高度.

Note: The fixed heights set in the custom CSS have been removed to allow the header/footer to be the height of their content, and the content row to fill the remaining height.
