如何以不同的方式安排3个div用于响应式设计

Question

我正在进行包含3 div s的页面重新设计，我想让它具有响应性。

我遇到的问题是大屏幕的div按照 1,2,3 的顺序排列。但是，对于响应式设计，我想将订单更改为 1,3,2 ：

我尝试了不同的方法，例如将position更改为relative / absolute / static或使用其他CSS代码更改div的顺序，但没有证明到目前为止工作。

我是如何实现这一目标的？

＆＃13;

＆＃13;

.one {
  float: left;
  width: 150px;
  border: solid 2px #eaeaea;
  position: relative;
  z-index: 0;
  margin-bottom: 20px;
  height: 100px;
}
.two {
  float: left;
  margin: 0 0 0 24px;
  width: 150px;
  border: solid 2px #eaeaea;
  height: 100px;
}
.three {
  float: left;
  width: 900px;
  border: solid 2px #eaeaea;
  height: 100px;
}
@media only screen and (max-width: 500px) {
  .one {
    width: 93%;
    padding: 3%;
  }
  .two {
    width: 100%;
    margin-left: 0px;
  }
  .three {
    width: 100%;
    margin: 0px;
  }
}

＆＃13;

<div class="one">Content1</div>
<div class="two">Content2</div>
<div class="three">Content3</div>

<div class="500markup">This box is 500px</div>

Answer 2

这可以使用flexbox：

来实现

• 将div设置为#container包含display: flex;，这将告诉孩子div使用flexbox模型
• 将flex: 1;添加到.one和.two，告诉他们如果需要增长
• 将flex-basis: 100%;添加到.three以确保占据容器的整个宽度
• 将order: *n*;添加到.one，.two和.three，以便在适应较小的屏幕尺寸时为其提供所需的顺序

＆＃13;

＆＃13;

#container {
  display: flex;
  flex-wrap: wrap;
  width: 100%;
}
.one {
  border: solid 2px #eaeaea;
  flex: 1;
  height: 100px;
  margin-bottom: 20px;
}
.two {
  border: solid 2px #eaeaea;
  flex: 1;
  height: 100px;
  margin-bottom: 20px;
}
.three {
  border: solid 2px #eaeaea;
  flex-basis: 100%;
  height: 100px;
  margin-bottom: 20px;
}
@media only screen and (max-width: 500px) {
  .one {
    flex-basis: 100%;
    order: 1;
  }
  .two {
    flex-basis: 100%;
    order: 3;
  }
  .three {
    flex-basis: 100%;
    order: 2;
  }
}

＆＃13;

<div id="container">
  <div class="one">Content1</div>
  <div class="two">Content2</div>
  <div class="three">Content3</div>
</div>
