[英]W3C validator : Element head is missing a required instance of child element title
您好我通過w3c驗證器驗證我的HTML代碼。 但它顯示錯誤元素頭缺少必需的子元素標題實例。
網址是http://nitansh.fwd.wf/article/travel/best-all-inclusive-resorts-for-romance/3189783/
雖然標題存在於html正文的頭部

只是為了您的信息，這是驗證器在您的代碼中看到的內容
<head>
<script src="//cdn.optimizely.com/js/687271175.js"></script>
<script src="http://code.jquery.com/jquery-1.11.0.min.js"></script>

</head>
您可以通過啟用驗證程序中的show source選項來查看此內容。 也許現在是時候研究漸進增強了嗎？
與您的其他問題相同的解決方案：
您正在使用JavaScript注入title元素，但W3C驗證程序不執行JavaScript。
