标签上方的广播

Question

我正在使用bootstrap v4并且有一系列自定义css样式的单选按钮，我已经设置了标签旁边的单选按钮。

然而，我现在想要创建一种新的风格，其中收音机位于标签上方并且居中，但我似乎无法获得正确的风格，因为我使用：之前。

第一个代码是收音机旁边的标签，第二个代码是我试图在标签上方设置收音机的样式

HTML

<div class="row">
  <div class="col-md-4">
    <div class="horizontal sau-select md selected">
      <input id="rad-1" class="sau-radio pt-2" name="radio-myg" type="radio" value="linux">
        <label for="rad-1" class="sau-radio-label pt-2">Linux</label>
    </div>
  </div>
  <div class="col-md-4">
    <div class="vertical sau-select md">

Answer 1

您可以将<input>置于<label>内，这是标准方式。

<label for="fruit2" class="sau-radio-label radio">
    <input type="radio" name="fruits" id="fruit2">
        Aligned Radio
</label>

您需要做的就是从输入中删除类sau-radio，然后从单选样式中删除单选按钮。
