Need quick way to validate proper nesting of HTML tags.

Question

Is there a firefox plugin or something similar I can use to validate that my html output has properly closed tags?

Answer 1

You can use either the W3 HTML Validator or HTML Tidy online.

Answer 2

I use this little guy Html Validator. I like him. The errors it makes help you find your nesting problems (along with others). I don't know of a validator that only checks for nesting issues.

Answer 3

If all you want to check is whether or not your tags are nested and closed properly (and not other things like that all images have an alt, etc), then you just want to check the XML well-formedness of it.

Run it through this validator http://www.validome.org/xml/ and tick the "Well-Formedness Only" checkbox.

Answer 4

The best is to install web developer tabs: https://addons.mozilla.org/en-US/firefox/addon/60

There you can find the link for validator and many other things.

Answer 5

I've been using the web developer addon for a long time.

https://addons.mozilla.org/en-US/firefox/addon/60

It's got an HTML validator link in the tools menu.
