Validation Error: Element hr not allowed as child of element ul in this context. (Suppressing further errors from this subtree.)

Question

我在 HTML Validator site 上遇到以下错误。

这是我收到的错误消息：

Element hr not allowed as child of element ul in this context. (Suppressing further errors from this subtree.)

这是我的 html 代码：

<nav>
    <ul>
        <li><a href="index.php">Home</a></li><hr>
        <li><a href="displayallbooks.php">Display All Books</a></li><hr>
        <li><a href="searchbooksform.php">Search Books</a></li><hr>
        <li><a href="credits.php">Credits</a></li><hr>

    </ul>   
</nav>

如有任何帮助，我们将不胜感激。谢谢。

基于 HTML 验证器，我在问题下方的评论和我在 Jsfiddle 上的尝试，将您的代码更改为：

<nav>
    <ul>
        <li><a href="index.php">Home</a><hr/></li>
        <li><a href="displayallbooks.php">Display All Books</a><hr/></li>
        <li><a href="searchbooksform.php">Search Books</a><hr/></li>
        <li><a href="credits.php">Credits</a><hr/></li>
    </ul> 
</nav>

我在 HTML validort 网站上使用的源代码是：

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en">
<head>
<title>t</title>
</head>
<body>
    <ul>
        <li><a href="index.php">Home</a><hr/></li>
        <li><a href="displayallbooks.php">Display All Books</a><hr/></li>
        <li><a href="searchbooksform.php">Search Books</a><hr/></li>
        <li><a href="credits.php">Credits</a><hr/></li>
    </ul> 
</body>
</html>

它给了我零错误。使用您的标签 nav，验证者投诉此标签。

Validation Error: Element hr not allowed as child of element ul in this context. (Suppressing further errors from this subtree.)
