为何‘Element div is not closed’报错无法消除？求技术帮助

你的代码存在两处未闭合的标签，导致了该错误：

• 外层的 <div class="banner"> 缺少对应的闭合标签 </div>
• <section class="welcome"> 缺少对应的闭合标签 </section>

以下是修正后的完整HTML代码：

<body>
  <!-- banner, navigation bar, logos which hyperlink to my socials -->
  <div class="banner">
    <div class="navbar">
      <a href="https://www.instagram.com/shegonnacode/"><img src="images/pngfind.com-instagram-png-22629.png" alt="Instagram logo" class="instagramlogo"></a>
      <a href="https://www.linkedin.com/in/paula-m-175737200/"><img src="images/pngfind.com-linkedin-png-533561.png" alt="Linkedin logo" class="linkedinlogo"></a>
      <ul>
        <li><a href="index.html">Home</a></li>
        <li><a href="resume.html">Resume</a></li>
        <li><a href="lists.html">Lists</a></li>
        <li><a href="contacts.html">Contact</a></li>
      </ul>
    </div>
    <!--About section begins-->
    <section class="welcome">
      <div class="content">
