根据设备宽度，使用CSS更改div顺序 [英] Change div order with CSS depending on device-width

问题描述

我在一个敏感的网站上工作，遇到一个有趣的问题。我有一些divs并排。可能有2到6个之间的任何地方。当屏幕不够宽以正确显示所有内容时，div垂直堆叠。对CSS很简单。

I am working on a responsive site and came across an interesting problem. I have some divs side by side. There could be anywhere from 2 to 6 or so of them. When the screen isn't wide enough to show all the content properly, the divs stack vertically. Simple enough to do with CSS.

问题是，我需要他们在不同的顺序，取决于布局。这是很容易做到2或3个div（根据宽度更改div顺序），但是当您添加第四个时显得更具挑战性。

The problem is, I need them to be in a different order depending on the layout. This is easy to do with 2 or 3 divs (Changing divs order based on width), but significantly more challenging when you add a fourth.

我可以使用 position：absolute;

为了使这个更复杂，我不能使用JavaScript。

To make this even more complicated, I can't use JavaScript.

HTML：

<div id="container">
    <div class="column-half column-half-2">
        First div on mobile, right div on desktop
    </div>
    <div class="column-half column-half-1">
        Second div on mobile, left div on desktop
    </div>
</div>

CSS：

.container {
    width: 80%;
    max-width: 1200px;
    margin: 0 auto;
    padding-bottom: 20px;
    position: relative;
}
.column-half {
    display: table-cell;
    padding: 25px;
    vertical-align: top;
    width: 40%;
}
.column-half-1 {
    float: left;
}
.column-half-2 {
    float: right;
}

HTML，4列：

HTML, with 4 columns:

<div id="container">
    <div class="column-quarter column-quarter-3">
        First div on mobile, third div on desktop
    </div>
    <div class="column-quarter column-quarter-2">
        Second div on mobile, second div on desktop
    </div>
    <div class="column-quarter column-quarter-1">
        Third div on mobile, first div on desktop
    </div>
    <div class="column-quarter column-quarter-4">
        Fourth div on mobile, fourth div on desktop
    </div>
</div>

推荐答案

a href =https://drafts.c​​sswg.org/css-flexbox-1/> flexbox 规范。使用 订单 和< a href =https://developer.mozilla.org/en-US/docs/Web/CSS/flex-flow> flex-flow 属性，我们可以实现你想要的。无预定义，IE11和所有常绿的浏览器将支持这一点。 IE10前缀 -ms-order ，不支持 flex-flow 。

This is doable in CSS now thanks to the wonderful flexbox spec. Using the order and flex-flow properties, we can achieve what you want. Unprefixed, IE11 and all evergreen browsers will support this. IE10 prefixes -ms-order and doesn't support flex-flow.

该解决方案考虑了您列出的所有约束：

The solution takes into consideration all the constraints you listed:

• 有给定顺序中的元素列表，显示为


• 当窗口太小时，将其更改为显示在列中。


• 更改元素的显示顺序

由于Stack Snippets的限制，您需要在全页面模式下查看演示，您的浏览器可查看效果。

Because of the limitations of Stack Snippets, you'll need to view the demo in Full page mode, and resize your browser to see the effect.

.container div {
    width: 100px;
    height: 50px;
    display: inline-block;
}

.one { background: red; }
.two { background: orange; }
.three { background: yellow; }
.four { background: green; }
.five { background: blue; }

@media screen and (max-width: 531px) {
    .container { display: flex; flex-flow: column; }
    .five { order: 1; }
    .four { order: 2;  }
    .three { order: 3; }
    .two { order: 4; }
    .one { order: 5 }
}

<div class="container">
    <div class="one">I'm first</div>
    <div class="two">I'm second</div>
    <div class="three">I'm third</div>
    <div class="four">I'm fourth</div>
    <div class="five">I'm fifth</div>
</div>
