HTML Checking for Large Sites
Rocket Validator automatically checks your pages on the W3C Validator.
HTML issues tagged as subtype missing.
The type
attribute on <a>
elements, when present, gives a hint on the MIME type of the linked resource, for example:
<a href="application/pdf" src="book.pdf">Read our book</a>
<a href="image/jpeg" src="photo.jpeg">See a photo</a>
That is, we’re talking about the type of the linked resource, not the type of the <a>
element, as it’s sometimes misunderstood. The following example is invalid because button
is not a valid MIME type.
<a href="/order.php" type="button">Submit</a>
