如果子级之一具有相对位置，则忽略“柔性方向”列

Question

我有下面的代码。

在.container上设置

display:flex;
flex-direction: column;

使我的previous和next箭头在容器items之前和之后移动。伸缩方向仍然行是行不通的。

.container {
  margin: 0;
  position: relative;
  overflow: hidden;
  border: 1px solid green;
  display: flex;
  flex-direction: column;
}

.items {
  left: 0;
  top: 0;
  display: flex;
  flex-direction: row;
  padding: 0.5rem 0;
  position: relative;
  margin: 2px;
}

.item {
  align-items: center;
  display: flex;
  height: 60px;
  justify-content: center;
  margin: 2px;
}

.item>* {
  cursor: pointer;
  display: flex;
  max-height: 100%;
}

.item img {
  display: block;
  max-height: 100%;
}

.previous::before,
.next::before {
  color: #9e9e9e;
  font: 400 1.5rem/1 iconfont !important;
  speak: none;
  text-transform: none !important;
}

<div class="container">
  <div class="previous">S</div>
  <div class="items">
    <div class="item">
      <a href="#"><img src="https://via.placeholder.com/50"></a>
    </div>
    <div class="item">
      <a href=""><img src="https://via.placeholder.com/50"></a>
    </div>
    <div class="item">
      <a href=""><img src="https://via.placeholder.com/50"></a>
    </div>
    <div class="item">
      <a href=""><img src="https://via.placeholder.com/50"></a>
    </div>
  </div>
  <div class="next">S</div>
</div>

Answer 1

实际上，您需要从flex-direction: column中删除.container，因为您正试图通过将箭头插入项目中来创建一行

.container {
  margin: 0;
  position: relative;
  overflow: hidden;
  border: 1px solid green;
  display: flex;
  align-items: center
}

.items {
  left: 0;
  top: 0;
  display: flex;
  padding: 0.5rem 0;
  position: relative;
  margin: 2px;
  flex: 1;
  background: lightblue;
  justify-content: center
}

.item {
  align-items: center;
  display: flex;
  height: 60px;
  justify-content: center;
  margin: 2px;
}

.item>* {
  cursor: pointer;
  display: flex;
  max-height: 100%;
}

.item img {
  display: block;
  max-height: 100%;
}

.previous::before,
.next::before {
  color: #9e9e9e;
  font: 400 1.5rem/1 iconfont !important;
  speak: none;
  text-transform: none !important;
}

<div class="container">
  <div class="previous">S</div>
  <div class="items">
    <div class="item">
      <a href="#"><img src="https://via.placeholder.com/50"></a>
    </div>
    <div class="item">
      <a href=""><img src="https://via.placeholder.com/50"></a>
    </div>
    <div class="item">
      <a href=""><img src="https://via.placeholder.com/50"></a>
    </div>
    <div class="item">
      <a href=""><img src="https://via.placeholder.com/50"></a>
    </div>
  </div>
  <div class="next">S</div>
</div>
