Re: [PLUG] HTML Validator

[Andrew Keyes <akeyes@gmail.com>]

HTML 4.01 strict (Why not skip ahead to 5?) requires elements, like input, to be in a block level tag (examples listed in your email). The easy solution would be to put a blank <div></div> around your input.

Unfortunately, I'm getting some strange error messages that I don't understand (not too surprising <grin>). I'm wondering if their validator is really telling me things I should know. For example, I have the statement:

Â

<FORM name="dummybutton" action="" method="get"><INPUT type="submit" value="" title="" ></FORM>

Â

[This is just a dummy placeholder for a menu selector that will appear on similar pages.]

Â

The validator gives me this error message:

Â

document type does not allow element "INPUT" here; missing one of "P", "H1", "H2", "H3", "H4", "H5", "H6", "PRE", "DIV", "ADDRESS" start-tag

âybutton" action="" method="get"><INPUT type="submit" value="" title="" ></FORM>

The mentioned element is not allowed to appear in the context in which you've placed it; the other mentioned elements are the only ones that are both allowed there and can contain the element mentioned. This might mean that you need a containing element, or possibly that you've forgotten to close a previous element.

One possible cause for this message is that you have attempted to put a block-level element (such as "<p>" or "<table>") inside an inline element (such as "<a>", "<span>", or "<font>").

Huh? When I changed to DOCTYPE 4.01 Transitional, the problem went away.

Â

Anybody have experience with the validator? I wanted to be "strict" in my HTML, but I'm thinking I'm just asking for trouble. Any comments/suggestions from this group?
