W3C验证器:元素头缺少子元素标题的必需实例

W3C validator : Element head is missing a required instance of child element title

本文关键字：元素 标题 实例 验证 W3C      更新时间：2023-09-26

嗨，我正在通过w3c验证器验证我的HTML代码。但它显示了一个错误，元素头缺少子元素title的必需实例。

URL为http://nitansh.fwd.wf/article/travel/best-all-inclusive-resorts-for-romance/3189783/

而标题出现在html主体的头部

<head>
<meta charset="UTF-8">

仅供参考，这是验证器在代码中看到的内容

<head>
<script src="//cdn.optimizely.com/js/687271175.js"></script>
<script src="http://code.jquery.com/jquery-1.11.0.min.js"></script>
<meta charset="UTF-8">
</head>

您可以通过打开验证器中的show source选项来看到这一点。也许是时候研究渐进增强了？

与您的另一个问题中的解决方案相同：

您正在用JavaScript注入title元素，但W3C验证器不执行JavaScript。
