HTML Checking for Large Sites

Rocket Validator integrates the W3C Validator HTML checker into an automated web crawler.

A closing tag </li> has been found, but there were open elements nested inside the <li>. You need to close the nested elements before you close the <li>.

A closing tag </li> has been found, but there were open elements nested inside the <li>. You need to close the nested elements before you close the <li>.

For example:

<li>
  <span>example
</li>

The above is invalid because you need to close the <span> tag before you close the <li>.

This would be valid:

<li>
  <span>example</span>
</li>
