求助：如何将垂直排列的Radio Button改为水平排列

原代码中单选按钮默认垂直排列，核心问题在于容器和单选按钮元素的块级布局设置，以下是修改方案：

原问题代码 #

HTML代码 #

<div class="x">
  <div class="radiobtn">
    <input type="radio" id="huey"
      name="drone" value="huey" checked />
    <label for="huey">Word</label>
  </div>

  <div class="radiobtn">
    <input type="radio" id="dewey"
      name="drone" value="dewey" />
    <label for="dewey">Powerpoint</label>
  </div>
              
  <div class="radiobtn">
    <input type="radio" id="louie"
      name="drone" value="louie" />
    <label for="louie">Speech</label>
  </div>

  <div class="radiobtn">
    <input type="radio" id="suey"
      name="drone" value="suey" />
    <label for="suey">Youtube</label>
  </div>

关键改动说明 #

1. 容器.x设置弹性布局：添加display: flex实现水平排列，gap控制元素间距，flex-wrap: wrap保证小屏幕下自动换行，同时扩大max-width避免空间不足。
2. 调整.radiobtn的显示方式：将display: block改为display: inline-block，配合flex布局实现水平排列。
3. 修正样式错误：原代码中font-weight: 400px是无效值，改为font-weight: 400；去掉label的margin-bottom，避免垂直间距影响水平布局。
4. 保留原有交互效果：所有单选按钮的选中动画、样式变化完全保留，仅修改布局方式。
