如何水平对齐复选框与单选框并实现文本左对齐？

第一步：调整HTML结构 #

当前代码里单选框文本在控件右侧，复选框全部嵌套在一个label内，需要调整结构满足需求：

<!DOCTYPE html>
<html lang="en">

<head>
  <meta charset="UTF-8">
  <title>Survey Registration Form</title>
  <link rel="stylesheet" href="survey.css">
</head>

<body>
  <div class="container">
    <h1 id="title">Pepe's Survey Form</h1>
    <p id="description">Thank you for taking time to help us improve the platform</p>
    <form method="post" action="https://register-demo.freecodecamp.org" id="survey-form">
      <fieldset>
        <label id="name-label">Enter your first name:<input class="form-control" id="name" type="text"
                                                                        placeholder="Enter your name" required></label>
        <label id="email-label">Email:<input class="form-control" id="email" type="email"
                                                         placeholder="Enter your email" required></label>
        <label id="number-label">Age(optional)<input class="form-control" id="number" type="number"
                                                                 placeholder="Enter your age" required min="18"
                                                                 max="100"></label>
        <label for="referrer">How did you hear about us?
                        <select class="dropdown" id="referrer" name="referrer">
                            <option disabled selected value>Select current trading style</option>
                            <option value="1">Intraday Trader</option>
                            <option value="2">Swing Trader</option>
                            <option value="3">Investor</option>
                        </select>
                    </label>
        <!-- 调整单选框结构：文本在前，input在后，每个label关联对应input -->
        <div class="inline-field">
          <label for="Yes" class="radio-label">Yes<input class="input-radio" id="Yes" name="Yes-No" checked
                                                          type="radio" value="Yes"></label>
          <label for="No" class="radio-label">No<input class="input-radio" id="No" name="Yes-No" type="radio"
                                                          value="No"></label>
        </div>

        <!-- 拆分复选框为独立label，文本在前，input在后 -->
        <label class="checkbox-group-label">What would you like to see improved?
          <small>(Check all that apply)</small>
        </label>
        <label for="more-charts" class="checkbox-label">More Charts<input class="input-checkbox" id="more-charts" type="checkbox" value="more-charts"></label>
        <label for="new-screener" class="checkbox-label">New Screener<input class="input-checkbox" id="new-screener" type="checkbox" value="new-screener"></label>
        <label for="better-execution" class="checkbox-label">Better execution speed<input class="input-checkbox" id="better-execution" type="checkbox" value="better-execution"></label>
        <label for="blog-page" class="checkbox-label">Blog Page<input class="input-checkbox" id="blog-page" type="checkbox" value="blog-page"></label>
        
        <label>Any comments or suggestions?
                        <textarea class="input-textarea" id="Textarea" rows="3" cols="30"
                                  placeholder="I want this feature.."></textarea>
                    </label>
        <label>
                        <input class="submit-button" id="submit" type="submit">
                    </label>
      </fieldset>
    </form>
  </div>
</body>

</html>

第二步：优化CSS样式 #

针对单选/复选框的布局问题，修改CSS如下：

.container {
  width: 100%;
  margin: 3.125rem auto 0 auto;
}

body {
  width: 100%;
  height: 100%;
  margin: 0;
  background: #1b1b32;
  color: white;
  font-family: Consolas, serif;
  font-size: 17px;
}

h1,
p {
  margin: 20px auto;
  text-align: center;
}

form {
  margin: 0 auto;
  width: 600px;
  max-width: 1000px;
  min-width: 300px;
  padding-bottom: 2em;
  padding-top: 1em;
  background-blend-mode: color;
}

fieldset {
  margin: auto;
  padding: 20px;
  border-radius: 30px;
  border-color: #6b6b8d;
}

label {
  display: block;
  margin: auto;
  text-align: left;
  font-size: 16px;
  padding-bottom: 10px;
  width: 100%;
}

input,
textarea,
select {
  box-sizing: border-box;
  width: 100%;
  min-height: 30px;
  margin: 10px 0 0 0;
  border-radius: 20px;
  border: 1px solid #0a0a23;
  background-color: #0a0a23;
  color: #ffffff;
  text-indent: 5px;
}

/* 重置单选/复选框样式：取消100%宽度，设置inline-block保证大小正常 */
.input-radio,
.input-checkbox {
  display: inline-block;
  margin: 0 8px 0 0;
  min-height: 1.25rem;
  min-width: 1.25rem;
  width: auto;
  vertical-align: middle;
}

/* 单选框容器：让内部选项水平排列 */
.inline-field {
  display: flex;
  gap: 20px;
  margin-bottom: 10px;
}

/* 单选/复选框的label：垂直居中对齐文本与控件 */
.radio-label,
.checkbox-label {
  display: flex;
  align-items: center;
  padding-bottom: 8px;
  width: auto;
}

/* 复选框组标题样式 */
.checkbox-group-label {
  margin-bottom: 8px;
}

.input-textarea {
  display: block;
  margin-left: auto;
  margin-right: auto;
  height: 120px;
  text-indent: 5px;
}

.submit-button {
  display: block;
  width: 50%;
  margin: 1em auto;
  height: 30px;
  font-size: 1.1rem;
  background-color: #3b3b4f;
  border-radius: 20px;
  border-color: #6b6b8d;
  min-width: 300px;
}

关键修改说明 #

• 结构调整：将单选/复选框的文本与input位置调换，实现文本在控件左侧；复选框拆分为独立label，确保每个选项可点击区域正确。
• 样式重置：取消单选/复选框继承的width:100%，设置width:auto和display:inline-block，避免控件被拉伸变形。
• 垂直对齐：给单选/复选框的label添加display:flex和align-items:center，让文本与控件垂直居中对齐。
• 水平排列：给单选框容器.inline-field设置display:flex和gap，实现选项水平分布且有间距。
