It's the same answer (1) for each bit. IDs are used to select and identify a particular element, so you can't have more than one.

I put (1) in the blank and was told every time that it was incorrect. What gives?

You don't need the parentheses, if you included them it'll likely mark it incorrect.

The logic is that you might use an ID once in your document, for whatever element you want to add it.

If you want to use the same ID on another element, you should use a class instead. Classes can be repeated, IDs can't.

Hi Awais,

I haven't seen the video, but this question looks like it's asking about the number of id's that can be applied to a single element and the number of times the same id can be used per page. Id's are unique (the same id cannot be used more than once on a page) and element can only have a single id.

Hope this helps.
