使用CSS重新排序DIV [英] Use CSS to reorder DIVs

问题描述

给定一个模板，其中由于其他要求不能修改HTML，如何在另一个 div上显示（重新排列） div 当它们不是在HTML中的顺序？ div 包含高度和宽度不同的数据。

Given a template where the HTML cannot be modified because of other requirements, how is it possible to display (rearrange) a div above another div when they are not in that order in the HTML? Both divs contain data that varies in height and width.

<div id="wrapper">
    <div id="firstDiv">
        Content to be below in this situation
    </div>
    <div id="secondDiv">
        Content to be above in this situation
    </div>
</div>
Other elements

希望结果很明显：

Content to be above in this situation
Content to be below in this situation
Other elements

当尺寸固定时，很容易将它们放在需要的位置，但是当内容可变时，我需要一些想法。对于这种情况，请考虑两者的宽度为100％。

When the dimensions are fixed it easy to position them where needed, but I need some ideas for when the content is variable. For the sake of this scenario, please just consider the width to be 100% on both.

编辑：CSS解决方案是最理想的解决方案。感谢您提供的Javascript选项。没有过于冗长的什么或为什么（或谁）...我专门寻找一个CSS的唯一解决方案（如果没有泛化，它可能需要满足其他解决方案）。

A CSS solution is the most ideal solution. Thank you for the Javascript options mentioned. Without getting too wordy about what or why (or who) ... I am specifically looking for a CSS only solution (and it will probably have to be met with other solutions if that doesn't pan out).

另一个...还有其他元素。我提到一个好的建议，因为我展示的有限场景 - 因为它可能是最好的答案，但我也希望确保后面的元素不会受到影响。

One more ... there are other elements following this. A good suggestion was mentioned given the limited scenario I demonstrated -- given that it might be the best answer, but I am looking to also make sure elements following this aren't impacted.

推荐答案

此解决方案仅使用CSS并适用于变量内容

This solution uses only CSS and works with variable content

#wrapper   { display: table; }
#firstDiv  { display: table-footer-group; }
#secondDiv { display: table-header-group; }
