html - 具有固定页眉和页脚以及可滚动内容的 Flexbox

Question

我正在尝试使 flexbox 设计工作。我不是 HTML/css 专家。 :(

我有一个 flexbox 设计，具有固定的页眉和页脚以及占据页面其余可用空间的内容。

当我将数据放入比可用空间长的内容区域时，内容正在滚动。但我想实现不同的目标。

我想在内容区域中有几个 div(彼此下方)并且每个 div 应该与内容区域一样高(即使内容很小)所以我在内容区域中有一种分页。

这几天我尝试了很多，也阅读了很多，但还是无法正常工作。如何让可滚动内容区域内的 div 占据整个空间(高度)？

你可以这样做:

html, body {
  margin: 0;
  height: 100%; /* can also use viewport units (height: 100vh) */
}

#container {
  display: flex; /* displays flex-items (children) inline */
  flex-direction: column; /* stacks them vertically */
  height: 100%; /* needs to take the parents height, alternative: body {display: flex} */
}

main {
  flex: 1; /* takes the remaining height of the "container" div */
  overflow: auto; /* to scroll just the "main" div */
}

section {
  height: 100%; /* takes the visible area of the "main" div */
  overflow: auto; /* recommended */
  border-bottom: 1px solid;
  background: lightgreen;
}

header {background: #f88}
section:last-child {border: none}
footer {background: lightblue}

<div id="container">
  <header>top</header>
  <main>
    <section>1st</section>
    <section>2nd</section>
    <section>3rd<br>
