HTML Checking for Large Sites
Rocket Validator integrates the W3C Validator HTML checker into an automated web crawler.
HTML issues tagged as anchor.
In the days before HTML5, named anchors were used as a way to provide a link to a specific section of a document, for example:
<h2>
<a name="section-5">Section 5</a>
</h2>
Now in HTML5, the name attribute is obsolete for <a> tags, and instead, you can use the id attribute of any element (not just <a>) as a way to navigate directly to it, for example:
<h2 id="section-5">Section 5</h2>
