将一个：checked伪类添加到嵌入的mailchimp表格中

Question

首先，我不是一个真正的Web开发人员，所以请耐心等待。

我试图在我的网站上嵌入mailchimp注册表单。除非选择了某个单选按钮，否则我想设置一个复选框来保持隐藏状态。

<style type="text/css">

} 

#radio-2:checked ~ .reveal { 
    display: inline; 
}

<!--End mc_embed_signup--> 

我想在这里设置复选框只显示何时第二个单选按钮被选中。

我可以得到：当我写我自己的表单时检查工作，但我似乎无法让它在嵌入式mailchimp表单中工作，我无法弄清楚为什么。有没有人有任何想法？

Answer 1

这里有几个问题：

1. 与!important规则的样式不能与其他的风格，不包括!important覆盖。您可以将其从第一种样式中移除以解决此问题。

2. ~兄弟CSS选择器定位元素with the same parent。由于广播和.reveal元素不共享相同的父元素，因此它不会显示.reveal元素。

3. 单选按钮不应该有两个id属性。当存在多个时，仅设置第二个id。

为了让兄弟选择工作，你可以从单选按钮删除<ul>和<li>元素，和他们之前添加换行符所以他们仍然在不同的行。还把.reveal类<div>里面的第一个.mc-field-group一个。这将使单选按钮具有与隐藏元素相同的父项。

下面是更新后的代码是什么样子：
