在多行中管理CSS flex-box增长以创建等块的网格 [英] Managing CSS flex-box growth in multi-line to create a grid of equal blocks

问题描述

我正在寻找一种方法，在使用 flex-growth：1 时，使用 flexbox / code>。这通过定义父对象很有用：

I am looking for a way to create equally sized boxes with flexbox while using flex-growth: 1. This works pretty good by defining the parent with:

display: flex;
flex-flow: row-wrap;

及其子级：

flex: 1 0 10rem;

但是，LAST行将（取决于该行中的块的数量）其框与上一行中的框相比。是否有办法解决这个问题，同时仍在使用flex-grow？

However, the LAST line will (depending on the amount of blocks in that line) have different widths for its boxes in comparison to the boxes in the previous lines. Is there a way to work around this while still using flex-grow?

<section>
    <div>aaaaaaaaaaaaaaaaaaaa</div>
    <div>bbbbbbbbbbbbbbbbbbbb</div>
    <div>cccccccccccccccccccc</div>
    <div>dddddddddddddddddddd</div>
    <div>eeeeeeeeeeeeeeeeeeee</div>
    <div>ffffffffffffffffffff</div>
    <div>gggggggggggggggggggg</div>
</section>

CSS

CSS

section {
    display: flex;
    flex-flow: row wrap;
    background-color: blue;
    width: 700px;
}

div {
    background-color: red;
    height: 100px;
    flex: 1 0 200px;
}

div:nth-child(even) {
    background-color: green;
}

http://jsfiddle.net/C2q8D/3/ 最后一行中的flex项目大于上面的行（因为该行上的项目较少划分空间）。

Note in http://jsfiddle.net/C2q8D/3/ that the flex items in the last line are bigger than the lines above (as there are less items on that line to divide the space).

推荐答案

这是完全可能的，但是，你必须知道你将有多少列最大值。 http://jsfiddle.net/kelunik/C2q8D/6/

This is totally possible, however, you have to know how many columns you'll have at a maximum. http://jsfiddle.net/kelunik/C2q8D/6/

通过添加几个空的占位符，您的卡的大小相同。你只需要确保，你添加了足够的占位符。

By adding a few empty placeholders, your cards get equally sized. You just have to make sure, you're adding enough placeholders. It doesn't matter if there are too many, because they'll have a height of zero and are not visible.

section {
    display: flex;
    flex-flow: row wrap;
    background-color: blue;
}

div {
    background-color: red;
    height: 3rem;
    flex: 1 0 10rem;
}

div:nth-child(even) {
    background-color: green;
}

div:empty {
    margin: 0;
    height: 0;
    border: 0;
    background: transparent;
}
