我有一个弹性盒子问题。谁能指出我正确的方向？甚至可能 flex-box 无法解决这种情况，因为它的工作方式。

  1. 我想跨 4 列显示内容。

  2. 让内容以柱状格式列出，并在空间不足时换行到下一列。

    display: flex; 
flex-direction: column; 
flex-wrap: wrap; 
height:<##>px

    应该注意这一点。

    但这就是事情变得棘手的地方。如果我不想要一个固定的高度，而是一个根据内容的长度增长/缩小的高度怎么办？

    在此处输入图像描述

  3. 让容器的高度是动态的。与案例 B 一样，行数从案例 A 中的 4 行增加到 7 行。内容被设置为尽可能填充所有列。

.other-nearby-cities {
  display: flex;
  flex-direction: column;
  height: 700px;
  flex-wrap: wrap;
  border: solid 1px;
}

您可以使用 CSS 列，高度将根据内容进行调整。

ul {
  column-count: 4;
  list-style: none;
  background: #eee;
}
<ul>
  <li>A</li>
  <li>B</li>
  <li>C</li>
  <li>D</li>
  <li>E</li>
  <li>F</li>
  <li>G</li>
  <li>H</li>
  <li>I</li>
  <li>J</li>
  <li>K</li>
  <li>L</li>
  <li>M</li>
  <li>N</li>
  <li>O</li>
  <li>P</li>
  <li>Q</li>
  <li>R</li>

如果 Flex 项目没有遇到容器的高度或宽度限制，它们将无法换行。此限制用作断点。否则，他们为什么要包装？如果没有固定的高度或宽度，它们就没有理由换行。

这在行方向上不是问题，因为默认情况下，块级元素仅限于其父级的宽度。因此，弹性容器最初实际上设置为width: 100%.

但是高度没有这样的限制。块级元素最初设置为height: auto，即其内容的高度。

因此，为了让弹性项目在列方向上换行，容器必须有一个固定的高度（height, max-height,flex-basis都可以）。

除了...如果布局跨越整个视口高度（这里似乎就是这种情况），那么只需要height: 100vh. 这允许高度既是动态的又是固定的。Flex 项目现在可以在列方向上换行。

.other-nearby-cities {
  display: flex;
  flex-direction: column;
  flex-wrap: wrap;
  height: 100vh;
  overflow: hidden;
  padding: 0;
  text-align: center;
}

li {
  width: 25%;
  padding: 10px;
  list-style-type: none;
}

* {
  margin: 0;
  box-sizing: border-box;
}
