Description Erik Rose 2010-07-13 16:51:36 UTC
When labeling a hidden input element in an HTML 5 document, the validator at returns the following error: "The for attribute of the label element must refer to a form control." Further discussion with the good folks who maintain the validator (, spilling over into the IRC exchange excerpted therein, suggests that the intent of the HTML 5 spec is that type=hidden inputs should not be labelable. This makes sense to me, since the intent is to pass focus from the label to the labeled element, but I do think the spec could benefit from some clarification.

In particular, according to, one can label any "labelable form-associated element", one of which is "input". I couldn't find any exceptions to this, for example at

Perhaps we could add something along the lines of "input (with a type attribute having a value other than hidden)" to the section at :

Labelable elements
    Denotes elements that can be associated with label elements.
        button input keygen meter output progress select textarea

...and also a note in .

Status: Partially Accepted
Change Description: see diff given below
Rationale: I added this constraint and noted it in the definition of "labelable". I didn't note it anywhere else so far, because the same constraint for "Interactive content" wasn't mentioned there either.

Looks great. To be totally pedantic, I noticed a missing space after the colon in "in the Hidden state:Listed". Thanks for the quick attention!
