如何让我的面板将屏幕填满页脚？ [英] How do I make my panel to fill the screen down to the footer?

问题描述

我希望我的面板占据所有屏幕直到页脚即使面板为空。
如果面板已填满，我想滚动查看内容，但页脚底部应始终显示页脚。
你有个主意吗？
以下是代码：

I want my panel to take up all the screen until the footer even if the panel is empty. If the panel is filled I want to scroll to see the content, but the footer should always be visible at the bottom of the page. Have you got an idea ? Here is the code :

.list_mobile .footer {
  position: absolute;
  bottom: 0;
  right: 0;
  width: 100%;
  height: 60px;
  background: lightskyblue;
  color: darkred;
}

<div class="row">
  <div class="col-xs-12 col-sm-12 col-lg-12 mg-tp-xs">
    <div class="panel panel-danger" style="overflow :scroll">
      <div class="panel-heading">
        <h4 class="panel-title">
          <span>Result</span>
        </h4>
      </div>
      <div class="panel-collapse">
        <div class="panel-body">
          <p>test</p>
        </div>
      </div>
    </div>
  </div>
</div>

<div class="list_mobile">
  <footer class="footer">
    <div class="container">
      <h4>number of results : 55 </h4>
    </div>
  </footer>
</div>

推荐答案

Bootstrap删除了 * - xs - * 类的所有变体。而不是 col-xs-12 ，使用 col-12 。由于所有尺寸的列都是100％，因此使用 col-12 就足够了。

Bootstrap has removed all the variants of *-xs-* classes. Instead of, col-xs-12, use col-12. Since the column is 100% for all sizes, it is enough to use col-12.

1. 使用 d-flex flex-column h-100 作为父母的行。


2. 对行使用 flex-grow-1 。


3. 行的所有父项必须为100％高度包括正文和html。


4. col-12 和 面板 必须 100％身高。


5. 使用 <$ c页脚的$ c>行 。


6. 不要更改页脚的位置：remove position：absolute;底部：0;右边：0;

1. Use d-flex flex-column h-100 for the parent of the row.
2. Use flex-grow-1 for the row.
3. All the parents of row must have 100% height including body and html.
4. col-12 and panel must have 100% height.
5. Use a row for the footer.
6. Do not change position of footer: remove position: absolute; bottom: 0;right: 0;

html,
body {
  height: 100%;
}

<link href="https://cdnjs.cloudflare.com/ajax/libs/twitter-bootstrap/4.1.1/css/bootstrap.css" rel="stylesheet"/>
<div class="container-fluid d-flex flex-column h-100 bg-primary">
  <div class="row flex-grow-1">
    <div class="col-12  bg-danger h-100">
      <div class="panel panel-danger h-100">
        <div class="panel-heading">
          <h4 class="panel-title">
            <span>Result</span>
          </h4>
        </div>
        <div class="panel-collapse">
          <div class="panel-body">
            <p>test</p>
          </div>
        </div>
      </div>
    </div>
  </div>

  <div class="row">
    <footer class="col-12 footer">
      <div class="container">
        <h4>number of results : 55 </h4>
      </div>
    </footer>
  </div>
</div>

您可以使用 container 而不是 container-fluid 。它没有任何区别。如果您这样做，请删除页脚中的容器。

You can use container instead of container-fluid. It does not make any difference. Buy if you do so,remove the container that is in the footer.

html,
body {
  height: 100%;
}

<link href="https://cdnjs.cloudflare.com/ajax/libs/twitter-bootstrap/4.1.1/css/bootstrap.css" rel="stylesheet"/>
<div class="container d-flex flex-column h-100 bg-primary">
  <div class="row flex-grow-1">
    <div class="col-12  bg-danger h-100">
      <div class="panel panel-danger h-100">
        <div class="panel-heading">
          <h4 class="panel-title">
            <span>Result</span>
          </h4>
        </div>
        <div class="panel-collapse">
          <div class="panel-body">
            <p>test</p>
          </div>
        </div>
      </div>
    </div>
  </div>

  <div class="row">
    <footer class="col-12 footer">
        <h4>number of results : 55 </h4>
    </footer>
  </div>
</div>
