html - 如何在标签下方水平对齐单选按钮

Question

所以我使用以下 HTML 在 jsp 中的各自标签下方水平居中显示 4 个单选按钮:

<s:form action="markUser" name="markUser" method="post" namespace="/secure/admin">
    <div id="radioGroup">

        <label for="markStudent">Mark User as Student</label>
        <input type="radio" name="mark" id="markStudent" value="Student" />

        <label for="markAdmin">Mark User as Admin</label>
        <input type="radio" name="mark" id="markAdmin" value="Admin" />

        <label for="markService">Mark User as Service</label>
        <input type="radio" name="mark" id="markService" value="Service" />

        <label for="markNull">Mark User as Null</label>
        <input type="radio" name="mark" id="markNull" value="Null" />

    </div>
</s:form>

和 CSS:

.radioGroup label {
  display: inline-block;
  text-align: center;
  margin: 0 0.2em;
}
.radioGroup label input[type="radio"] {
  display: block;
  margin: 0.5em auto;
}

但我一直收到如下所示的错位按钮

我可能在这里遗漏了什么？

Answer 1

据我了解，你想要这个

#radioGroup .wrap {
  display: inline-block;
}
#radioGroup label {
  display: block;
  text-align: center;
  margin: 0 0.2em;
}
#radioGroup input[type="radio"] {
  display: block;
  margin: 0.5em auto;
}

<div id="radioGroup">
  <div class="wrap">
    <label for="markStudent">Mark User as Student</label>
    <input type="radio" name="mark" id="markStudent" value="Student" />
  </div>

  <div class="wrap">
    <label for="markAdmin">Mark User as Admin</label>
    <input type="radio" name="mark" id="markAdmin" value="Admin" />
  </div>
  <div class="wrap">
    <label for="markService">Mark User as Service</label>
    <input type="radio" name="mark" id="markService" value="Service" />
  </div>
  <div class="wrap">
    <label for="markNull">Mark User as Null</label>
    <input type="radio" name="mark" id="markNull" value="Null" />
  </div>
</div>

注意:

这在两个方面是不正确的:

.radioGroup label input[type="radio"] {
  display: block;
  margin: 0.5em auto;
}

首先，该元素的 ID 是 radioGroup 而不是类

其次，输入不是标签的子，而是兄弟
