如何使用flexbox实现包含侧边栏内容的浮动侧边栏布局？

Question

如何使用flexbox实现包含侧边栏内容的浮动侧边栏布局？

Ser*_*y K 3 html css css3 flexbox

我正在尝试在桌面上实现响应式布局:

在移动设备上这样:

请注意以下要求:

边栏应该只占用适合内容所需的垂直空间.在侧边栏下方,主要部分的内容应占据整个宽度.
在移动设备上,侧边栏应显示在主要内容下方.

这是一个包含我的初始HTML和CSS的jsfiddle:

和一个片段:

body {
  font-family: "Helvetica Neue", Helvetica, Arial, sans-serif;
  font-size: 14px;
  padding: 0 2em;
  line-height: 1.4;
  color: #333;
  background-color: #fff
}

section {
  margin: 1.6em 0;
}

section>h2 {
  margin: 0;
  padding: 12px 24px;
  font-size: 16px;
  background: #eceeee;
  text-transform: uppercase;
}

section>p {
  margin: 0;
  padding: 12px 24px;
  background: #fafafa;
}

.container {
  display: flex;
  flex-wrap: wrap;
}

main {
  flex-basis: 100%;
}

.sidebar {
  padding: 0 2em;
  background: #fbf6f4;

@media screen and (min-width: 1024px) {

  main {

  }
  .sidebar {

请注意,侧边栏下方有浪费的空间.我希望主要内容在侧边栏结束后环绕并占据整个宽度,但我不确定如何实现.

我想float: right在侧边栏上使用并将其放在前面<main>,但这会导致侧边栏首先出现在移动设备上(我希望它出现在内容之后).

有没有办法在给定上述要求的情况下实现所需的布局,使用flexbox,float还是其他技术？

你可以切换display和order使用float.为了使用float你需要aside首先在HTML中,所以内容可以包装.flex并将order在移动设备上发回底部.

下面的示例或代码片段,其中包含HTML更新,以便从flex布局切换到浮动布局

body {
  font-family: "Helvetica Neue", Helvetica, Arial, sans-serif;
  font-size: 14px;
  padding: 0 2em;
  line-height: 1.4rem;
  color: #ddd;
  background-color: #333
}

section {
  color:#333;
  margin: 1.6em 0;
}

section > h2 {
  margin: 0;
  padding: 12px 24px;
  font-size: 16px;
  background: #ace;
  text-transform: uppercase;
}

section > p {
  margin: 0;
  padding: 12px 24px;
  background: #fafafa;
}

.container {
overflow:hidden;
}

main {
  display:flex;
  flex-direction:column;
}

.sidebar {
  padding: 0 2em;
  background: tomato;
  order:2;
}

@media screen and (min-width: 1024px) {
  .container {
  }
  
  main {
    display:block;
  }
  main h1 {
    float:left;
    width:70%;
  }
  main section {
    clear:left;
    overflow:hidden;
  }
  
  .sidebar {
    width:25%;
    float:right;
    margin-left:2em;
  }
}
