css - Radiobutton 仅适用于一种形式，其他形式不能

Question

我正在尝试修改输入类型 radio 的输入样式，并且我有两种不同形式的 radio 输入。但 radio 输入仅适用于第一种形式，而第二种形式无效。我仍然对为什么不在第二个上工作这个问题感到困惑。

请帮帮我。提前致谢

<input type="radio" name="roundtrip" id="oneway" value="oneway" checked="">
<label for="oneway">Oneway</label>

[type="radio"]:checked,
[type="radio"]:not(:checked) {
  position: absolute;
  left: -9999px;
}

[type="radio"]:checked + label,
[type="radio"]:not(:checked) + label {
  position: relative;
  padding-left: 28px;
  cursor: pointer;
  line-height: 20px;
  display: inline-block;
  color: #666;
}

[type="radio"]:checked + label:before,
[type="radio"]:not(:checked) + label:before {
  content: '';
  position: absolute;
  left: 0;
  top: 0;
  width: 18px;
  height: 18px;
  border: 1px solid #ddd;
  border-radius: 100%;
  background: #fff;
}

[type="radio"]:checked + label:after,
[type="radio"]:not(:checked) + label:after {
  content: '';
  width: 12px;
  height: 12px;
  background: #F87DA9;
  position: absolute;
  top: 4px;
  left: 4px;
  border-radius: 100%;
  -webkit-transition: all 0.2s ease;
  transition: all 0.2s ease;
}

[type="radio"]:not(:checked) + label:after {
  opacity: 0;
  -webkit-transform: scale(0);
  transform: scale(0);
}

[type="radio"]:checked + label:after {
  opacity: 1;
  -webkit-transform: scale(1);
  transform: scale(1);
}

Answer 1

Id 必须是唯一的。因此，请在 radio 输入中提供唯一的 id。

[type="radio"]:checked,
[type="radio"]:not(:checked) {
  position: absolute;
  left: -9999px;
}

[type="radio"]:checked + label,
[type="radio"]:not(:checked) + label {
  position: relative;
  padding-left: 28px;
  cursor: pointer;
  line-height: 20px;
  display: inline-block;
  color: #666;
}

[type="radio"]:checked + label:before,
[type="radio"]:not(:checked) + label:before {
  content: '';
  position: absolute;
  left: 0;
  top: 0;
  width: 18px;
  height: 18px;
  border: 1px solid #ddd;
  border-radius: 100%;
  background: #fff;
}

[type="radio"]:checked + label:after,
[type="radio"]:not(:checked) + label:after {
  content: '';
  width: 12px;
  height: 12px;
  background: #F87DA9;
  position: absolute;
  top: 3px;
  left: 3px;
  border-radius: 100%;
  -webkit-transition: all 0.2s ease;
  transition: all 0.2s ease;
}

[type="radio"]:not(:checked) + label:after {
  opacity: 0;
  -webkit-transform: scale(0);
  transform: scale(0);
}

[type="radio"]:checked + label:after {
  opacity: 1;
  -webkit-transform: scale(1);
  transform: scale(1);
}
ul{
  list-style:none;
}
