Can an html element have multiple ids?

Question

I understand that an id must be unique within an HTML/XHTML page.

My question is, for a given element, can I assign multiple ids to it?

Answer 1

No. Every DOM element, if it has an id, has a single, unique id. You could approximate it using something like:

and then use navigation to get what you really want.

If you are just looking to apply styles, class names are better.
