I can't recommend a tutorial, but I could suggest finding any older 'learn HTML in 24 hours' from before frameworks were a thing (pre-2010) and get a firm grasp of the basic language. Creating a server-side thing to interact with is another level of depth, since you'll have end up choosing a language or system to learn in addition to HTML...older books will probably have you using something like Perl to submit forms to, so you might desire to pick up a more modern technology.
