【问题描述】：

我想设置我的注册表单的样式，使背景颜色不会仅覆盖注册表单内部的图例标记。

例如，这就是我想要实现的目标：

这是我的结果：

我当前的代码：

#signupform 
  font-size: 2rem;
  margin: 30px;
  line-height: 50px;
  background-color: #f6f6f6;


#signupform legend 
  font-size: 3rem;

<section class="subscribe">
  <h2>SUBSCRIBE</h2>
  <p>Sign up to our newsletter and receive exclusive offers by email weekly.</p>
  <form id="signupform">
    <fieldset>
      <legend>SIGN UP NOW!</legend>

      <label for="name">Your name:</label>
      <input type="text" name="name" id="name">

      <label for="mail">Email address:</label>
      <input type="text" name="mail" id="mail">
      <button type="button" class="signupbutton">Sign up</button>
    </fieldset>
  </form>
</section>

【参考方案1】：

你必须在fieldset中设置background-color

#signupform 
  font-size: 2rem;
  margin: 30px;
  line-height: 50px;


fieldset 
  background-color: #f6f6f6;


#signupform legend 
  font-size: 3rem;

<section class="subscribe">
  <h2>SUBSCRIBE</h2>
  <p>Sign up to our newsletter and receive exclusive offers by email weekly.</p>
  <form id="signupform">
    <fieldset>
      <legend>SIGN UP NOW!</legend>
      <label for="name">Your name:</label>
      <input type="text" name="name" id="name">
      <label for="mail">Email address:</label>
      <input type="text" name="mail" id="mail">
      <button type="button" class="signupbutton">Sign up</button>
    </fieldset>
  </form>
</section>
