Flex-box:将最后一行与网格对齐 [英] Flex-box: Align last row to grid

问题描述

我有一个简单的 flex-box 布局，其中包含一个容器，例如:

.grid {显示:弹性；flex-flow:行包装；对齐内容:间隔；}

现在我希望最后一行中的项目与另一行对齐.应该使用 justify-content: space-between; 因为可以调整网格的宽度和高度.

目前看起来像

在这里，我希望右下角的项目位于中间列"中.实现这一目标的最简单方法是什么?这是一个显示这种行为的小 jsfiddle.

.exposegrid {显示:弹性；flex-flow:行包装；对齐内容:间隔；}.exposetab {宽度:100px；高度:66px；背景颜色:rgba(255, 255, 255, 0.2);边框:1px 实心 rgba(0, 0, 0, 0.4);边框半径:5px；box-shadow: 1px 1px 2px rgba(0, 0, 0, 0.2);底边距:10px；}

<div class="exposetab"></div><div class="exposetab"></div><div class="exposetab"></div><div class="exposetab"></div><div class="exposetab"></div><div class="exposetab"></div><div class="exposetab"></div><div class="exposetab"></div><div class="exposetab"></div><div class="exposetab"></div><div class="exposetab"></div><div class="exposetab"></div><div class="exposetab"></div><div class="exposetab"></div>

解决方案

添加 ::after 自动填充空间.无需污染您的 HTML.这是一个显示它的代码笔:http://codepen.io/DanAndreasson/pen/ZQXLXj

.grid {显示:弹性；flex-flow:行包装；对齐内容:间隔；}.grid::after {内容: "";弹性:自动；}

I have a simple flex-box layout with a container like:

.grid {
  display: flex;
  flex-flow: row wrap;
  justify-content: space-between;
}

Now I want the items in the last row to be aligned with the other. justify-content: space-between; should be used because the width and height of the grid can be adjusted.

Currently it looks like

Here, I want the item in the bottom right to be in the "middle column". What is the simplest way to accomplish that? Here is a small jsfiddle that shows this behaviour.

.exposegrid {
  display: flex;
  flex-flow: row wrap;
  justify-content: space-between;
}

.exposetab {
  width: 100px;
  height: 66px;
  background-color: rgba(255, 255, 255, 0.2);
  border: 1px solid rgba(0, 0, 0, 0.4);
  border-radius: 5px;
  box-shadow: 1px 1px 2px rgba(0, 0, 0, 0.2);
  margin-bottom: 10px;
}

<div class="exposegrid">
  <div class="exposetab"></div>
  <div class="exposetab"></div>
  <div class="exposetab"></div>
  <div class="exposetab"></div>
  <div class="exposetab"></div>
  <div class="exposetab"></div>
  <div class="exposetab"></div>
  <div class="exposetab"></div>
  <div class="exposetab"></div>
  <div class="exposetab"></div>
  <div class="exposetab"></div>
  <div class="exposetab"></div>
  <div class="exposetab"></div>
  <div class="exposetab"></div>
</div>

解决方案

Add a ::after which autofills the space. No need to pollute your HTML. Here is a codepen showing it: http://codepen.io/DanAndreasson/pen/ZQXLXj

.grid {
  display: flex;
  flex-flow: row wrap;
  justify-content: space-between;
}

.grid::after {
  content: "";
  flex: auto;
}
