Html 我无法找出这些错误

第80行第16列：显示了结束标记形式，但存在开放元素。 第42行第27列：未闭合元素字段集。 第80行第16列：上次出错后无法恢复。

开始时，使用“p”-标记。如果我没看错的话，你永远不会把它关上。您交换了结束文件集和表单标记。

长话短说，您有这样的表单结构：

<p><form action="http://ctec.clark.edu/CTEC122/scripts/form_echo.php" method="post">
    <fieldset id="fieldset2">

                <label id="label2" for="street">Street:</label>
                    <input type="text" name="street" id="street" size="50">

您正在关闭

之前的

标记。将

标签放在末尾，同时确保关闭

标签。

。另外，“无法找出这些错误”也很有趣。根据W3C规范，关闭

p

标记可以省略。
