我希望我的数据按列排列(从上到下,从左到右),数据中的每个标题都应该开始一个新的列.有三个限制:
>必须使用flex(我需要使用特定于flex的功能)
>无法对数据进行分组(例如,将所有数据项包含在一个div内)
>无法设定固定高度
我的问题是如何在flex-flow:列换行布局中强制列中断?
.grid { display: flex; flex-direction: column; flex-wrap: wrap; } .grid .head { width: 25%; background: orange; border-bottom: thin dotted; } .grid .data { width: 25%; background: yellow; border-bottom: thin dotted; } /* my attempt to solve this */ .grid { height: 76px; }
<div class="grid"> <div class="head">Column 1 (3 items)</div> <div class="data">item 1-1</div> <div class="data">item 1-2</div> <div class="data">item 1-3</div> <div class="head">Column 2 (4 items)</div> <div class="data">item 2-1</div> <div class="data">item 2-2</div> <div class="data">item 2-3</div> <div class="data">item 2-4</div> <div class="head">Column 3 (2 items)</div> <div class="data">item 3-1</div> <div class="data">item 3-2</div> <div class="head">Column 4 (1 items)</div> <div class="data">item 4-1</div> </div>
解决方法
显然,the correct solution is to use the
break-before
or break-after
property:
A break is forced wherever the CSS2.1
07001/07002 [CSS21] or the CSS3
07003/07004 [CSS3-BREAK] properties specify a
fragmentation break.
在撰写本文时,大多数浏览器都会错误地实现* -break- *属性,或者根本不实现它们.在此之前考虑这个答案.
以下演示工作原理:
> FF33
.grid { display: flex; flex-direction: column; flex-wrap: wrap; } .grid .head { width: 25%; background: orange; border-bottom: thin dotted; } .grid .data { width: 25%; background: yellow; border-bottom: thin dotted; } /* force column breaks */ .grid .head:nth-child(n + 2) { page-break-before: always; /* FF33 */ }
<div class="grid"> <div class="head">Column 1 (3 items)</div> <div class="data">item 1-1</div> <div class="data">item 1-2</div> <div class="data">item 1-3</div> <div class="head">Column 2 (4 items)</div> <div class="data">item 2-1</div> <div class="data">item 2-2</div> <div class="data">item 2-3</div> <div class="data">item 2-4</div> <div class="head">Column 3 (2 items)</div> <div class="data">item 3-1</div> <div class="data">item 3-2</div> <div class="head">Column 4 (1 items)</div> <div class="data">item 4-1</div> </div>
