Question

我正在实现一个带有粘性页脚的flexbox布局。我在min-height:100vh和body上有一个.content-container来保存内容。我还有header和footer没有设置高度。我的问题是页脚设置在页面底部下方，即使没有内容。我已调整min-height:100vh以将页脚放在底部，但随后移动内容会超出footer。在所有情况下如何将footer置于底部？

HTML

<header class="page_header">
  <h1>Scoreboard</h1>
</header>

<div class="content_container">
  <main class="content">
    <h2>Visualized Votes</h2>
    <div id="graph_container">

    </div>
  </main>
  <aside class="left_container">
    <h2>Recent Votes</h2>
    <div class="recent_votes_container"></div>
  </aside>
  <aside class="right_container">
    <h2>Top Votes</h2>
    <div class="top_votes_container"></div>
  </aside>
</div>
<footer class="page_footer">

CSS

* {
  box-sizing: border-box;
}

body {
  background-color: #f6f1ed;
  display: flex;
  min-height: 100vh;
  flex-direction: column;
}

header.page_header {
  width: 100%;
  background-color: #30231d;
}

header h1 {
  font-family: 'Lobster Two', cursive;
  font-size: 60px;
  color: #fff;
  padding: 20px;
  text-align: center;
}

main, aside {
  margin-bottom: 30px;
}

  margin: .5em;
  text-transform: capitalize;
  text-align: center;
  border-top-left-radius: 15px;
  border-top-right-radius: 15px;
}

main p, aside p {
  padding: 1em;
  margin: .5em .5em .3em;
}

footer.page_footer {
  background-color: #6a5750;
  font-family: 'Lobster Two', cursive;
  font-size: 20px;
  color: #fff;
  padding: 10px;
  text-align: center;
}

.content_container {
  display: flex;
  flex: 1;
  min-height: 100vh;
  flex-direction: column;
}

main {
  flex: 1;
}

.left_container {
  flex: 1;
  flex: 0 0 15em;
  order: -1;
}

.right_container {
  flex: 0 0 15em;
}

.recent_votes_container, .top_votes_container {
  text-align: center;
}

.recent_votes_container li, .top_votes_container li {
  list-style-type: none;
}

@media (min-width: 768px) {
  .content_container {
    flex-direction: row;
    flex: 1;
  }
  .content_container {
    flex: 1;
  }
}

Answer 1

删除以下代码。它使页脚的上一个兄弟太高了，所以页脚被推得太多了。

.content_container {
  min-height: 100vh;
}

此外，body默认有一些余量，但min-height: 100vh不包括它。删除保证金或将其考虑在内。

Flexbox粘性页脚延伸到页面底部，没有内容
