Rocket Validator integrates the W3C Validator HTML checker into an automated web crawler.
HTML issues tagged as end tag.
An </a> end tag has been found to violate nesting rules. <a> tags can’t include other <a> tags inside. Most probable cause is an unclosed <a> tag, like in this example:
<a href="one.html">Page 1 <a href="two.html">Page 2</a>
An end tag </code> has been found violating nesting rules. Check other errors in the same document related to the <code> element, and fix the unallowed nested elements.
A closing </body> tag has been found, but there are unclosed elements before it. For example this has an unclosed <section> element:
<body> <section> </body>
And end tag has been found that does not match the current open element. Check the context to fix the start and end tags.
An end tag has been found after the closing </body> tag, which breaks the expected HTML document structure.
Check out the document structure, a basic example follows:
<!DOCTYPE html> <html lang=""> <head> <title>Test</title> </head> <body> <p></p> </body> </html>
An end tag for X has been found that does not correspond to a previous open tag. This usually happens when you close the same tag twice, for example:
<ul> <li>item</li> </ul> </ul>
