HTML Checking for Large Sites
Rocket Validator integrates the W3C Validator HTML checker into an automated web crawler.
HTML issues tagged as open elements.
An end tag has been implied from the context, but there were open elements. Check other issues in the same document for open tags that need to be closed.
For example, the following will raise a “end tag li implied” issue, because the span element inside the li has not been properly closed.
<ul> <li><span>text<li> </ul>
Instead, this is correct:
<ul> <li><span>text</span><li> </ul>
