Question

HTML can use a “#name” link to direct users to named anchor elements, like <a name="name">. Is it possible to link to any other attributes, like id or class? How about HTML5 stuff like ‘itemprop’ or ‘content’ ?

Answer 1

Yes, and indeed it’s preferred to use the id of an element to create an internal link within a page.

Example markup:

<a href="#part2">Part 2</a>

<!-- other html -->

<h2 id="part2">This is part 2</h2>

It’s worth noting that a link can connect to only one, unique, target, therefore a class (or other attribute) cannot be used as all non-id attributes may be shared/replicated across many elements. Whereas an id must be unique within the document.
