Question

我有一个奇怪的案例：

我尝试制作一个内部容器来填充父级（高度为100％的高度），但结果我在底部得到溢出的内容：

enter image description here

但必须如此（100％除边缘顶部和底部）：

enter image description here

代码：

<!DOCTYPE html>
<html>

  <head>
    <link rel="stylesheet" href="style.css">
    <script src="script.js"></script>
  </head>

  <body>
    <div class="main-wrapper">
      <aside class="full-nav" action-bar>
        </aside>
      <section class="wrapper">
            <header>
            </header>
        <div class="content">
          <div class="innner-wrapper">
            <div class="main-partial">
                <div class="content-wrapper">Content</div>
            </div>
          </div>
        </div>
      </section>
    </div>
  </body>

</html>

（当我设置绝对位置时，我得到奇怪的宽度...）

Answer 1

您可以计算.content-wrapper的高度并进行调整。

.content-wrapper {
   height: calc(100% - 70px);
}
