我有一个切换按钮。但它不适用于输入类型的收音机。如果我尝试使用复选框按钮，它会起作用。为什么？我该如何解决，保持无线电输入？

我希望 .c 窗口在切换时改变背景颜色

【问题讨论】：

您有一些拼写错误，例如.switch input~:checked、.switch input~:checked~.toggle。此外，input[type="radio"]:checked ~ .c-window 不起作用，因为它们不是兄弟姐妹
我编辑了 .switch input:checked ~ .c-window { background: #111; }但它还没有工作
但您的 input:checked 和您的 .c-window 仍然不是兄弟姐妹。欲了解更多信息，请参阅developer.mozilla.org/en-US/docs/Web/CSS/…
我把下面的 c-window 放到输入中，所以理论上它们现在是兄弟姐妹。但是，如果我这样做并刷新页面，则圆圈会立即变为黑色背景并且不会更改
如果您对上面的代码进行了一些更改，请将修改后的代码放在 fiddle 中，以便我们可以看到相同的内容

标签： html css input checked

【解决方案1】：

@fcalderan 在 cmets 中提到，您有一些拼写错误。
您需要将.c-window 作为同级，更改HTML 标记并将z-index:-1 添加到其中。
您需要指定哪个input 将更改background 颜色。

【解决方案2】：

你不能用 javascript/jQuery 来做吗？

HTML：

<div class="container">

   <div class="c-window"></div>

    <div class="switch white">

        <input type="radio" name="switch" value="0" id="switch-off" class="switch">
        <input type="radio" name="switch" value="1" id="switch-on" class="switch" checked>

        <label for="switch-off">On</label>
        <label for="switch-on">Off</label>

        <span class="toggle"></span>

    </div> <!-- end switch -->

</div> <!-- end container -->

jQuery（捕捉更改事件）：

    $(document).ready(function(){
$('.switch').on('change', function(ev){
if ($(this).val() == 0){
//do some stuff you want when off
}else{
//do some stuff you want when on
}
});
});

【讨论】：

OP 既没有提到 javascript 也没有提到 jQuery。
@NagyIstvan 看到我的答案
正确使用 :checked 伪类作为 OP 尝试执行的操作（另请参阅之前的答案）

【解决方案3】：

如果你想使用~ 选择器，你的代码应该是这样的

body, html {
  margin: 0;
  padding: 0;
}

.content {
  display: flex;
  height: 100vh;
  align-items: center;
  justify-content: center;
  position: relative;
}

.c-window {
  position: absolute;
  transition: all 0.3s ease-in;
  width: 235px;
  height: 235px;
  border-radius: 50%;
  left: 50%;
  top: 50%;
  transform: translate(-50%, -50%);
  background: #aaa;
  border: 5px solid black;
  z-index: 1;
}

input {
  position: relative;
  z-index: 2;
}

#switch-off:checked ~ .c-window  {
  background: blue;
}

#switch-on:checked ~ .c-window  {
  background: #aaa;
}

<div class="content">
  <input type="radio" name="switch" id="switch-off">
  <input type="radio" name="switch" id="switch-on" checked>
  
  <div class="c-window"></div>
</div>
