使用带有复选框的纯 css 手风琴，您可以打开和关闭所有打开的标签页吗？

如何解决使用带有复选框的纯 css 手风琴，您可以打开和关闭所有打开的标签页吗？

代码来自这里 --> https://codepen.io/raubaca/pen/PZzpVe

我已经查看了类似问题的其他答案。实际上没有什么能充分回答这个问题。或者它们是关于稍微收敛的问题，或者使用 jquery 等，或者使用不同格式的 css。

当使用checkBox方法制作一个可以同时打开多个标签的纯css手风琴时，是否可以一次关闭所有标签？还要同时打开所有标签？我假设我可以执行类似 input:unchecked ~ .tab-content {...} 的操作，但是 css 规范中没有 input:unchecked。

解决方法

仅使用 css 可以做的最好的事情就是全部打开 - 您将无法关闭所有内容（只需将它们恢复到原始状态）。首先，您需要将切换复选框移到选项卡外，使其与手风琴选项卡处于同一级别，然后您可以使用以下代码段末尾的三种样式

如果需要全部关闭，则必须使用 js 取消选中已选中以打开它们的复选框 - css 不能这样做

实际上，您可以将其扩展为使用单选按钮作为切换按钮，然后您也可以关闭所有按钮：
