HTML Checking for Large Sites

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

No space between attributes.

Attributes in HTML elements need to be separated by space, in this example the first line is invalid and the second one is valid:

<a href="page.php"class="big">link</a>

<a href="page.php" class="big">link</a>
