纯CSS折叠/展开div [英] Pure CSS collapse/expand div

问题描述

我有一个纯CSS可折叠的div是基于别人的代码，使用：target psuedoclass。我想设置的是一个页面有12个以上的问题，当你点击+按钮，答案div扩展下面。我不知道如何使多个折叠div元素在这个页面上，没有编写一个额外的CSS。任何人都有建议如何写这个，所以我的CSS代码最小化？ （即，我不必为12个以上的问题中的每一个输入一组唯一的选择器）。

I have a pure CSS collapsable div which is based on someone else's code who uses the :target psuedoclass. What I am trying to set up is a page with 12+ questions, and when you click on the + button the answer div expands beneath. I cannot figure out how to make multiple collapsing div elements on this page without writing a ton of extra CSS. Anyone have suggestions on how to write this so my CSS code is minimized? (i.e., so i dont have to input a bunch of unique selectors for each of the 12+ questions).

我不能使用Javascript，因为这是一个wordpress。 com网站不允许JS。

I cannot use Javascript since this is going on a wordpress.com site which does not allow JS.

推荐答案

您希望获得支持，或者您准备好接受不符合规范的浏览器，您可以查看< summary> 和< detail> 标签。他们正是为了这个目的。不需要css，因为折叠和显示是标签定义/格式化的一部分。

Depending on what browsers/devices you are looking to support, or what you are prepared to put up with for non-compliant browsers you may want to check out the <summary> and <detail> tags. They are for exactly this purpose. No css is required at all as the collapsing and showing are part of the tags definition/formatting.

我举了一个例子在这里：

<details>
<summary>This is what you want to show before expanding</summary>
<p>This is where you put the details that are shown once expanded</p>
</details>

浏览器支持尝试webkit以获得最佳结果。其他浏览器可能默认显示所有解决方案。您可以回退到上述隐藏/显示方法。

Browser support varies. Try in webkit for best results. Other browsers may default to showing all the solutions. You can perhaps fallback to the hide/show method described above.
