具有固定页眉和页脚以及可滚动内容的Flexbox

Question

我正在努力使Flexbox设计工作.我不是HTML/css专家.:(

我有一个固定页眉和页脚的Flexbox设计和内容占据了页面的其余可用空间.

当我将数据放入比该可用空间更长的内容区域时,内容将滚动.但我希望实现另一件事.

我想在内容区域中有几个div(彼此之下),每个div应该与内容区域一样高(即使内容很小),所以我在内容区域内有一种分页.

有几天我尝试了很多并且阅读了很多但却无法使用它.如何在可滚动内容区域内创建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>
