These tutorials were with the HTML tutorial. I didn't think they belong with the "beginner's" HTML tutorials because these are somewhat confusing or maybe not really necessary to know. To fully understand how to work with forms, one must know how to work with form handlers. Apparently, form handlers are covered in the PHP and ASP tutorials. I just don't want to learn about that right now, because I'm not sure if I ever would be using forms on my webpages.
As for the HTML5 stuff, well... because I'm a bit of a perfectionist, I think it's a great thing! I love it! However, I think many amateur webpage designers might stick with HTML4 or tackle XHTML. So, I thought HTML5 belongs to the "advanced" section, since it is the newest version of markup language. It will eventually replace XHTML (a combination of HTML4 and XML).
I really wanna get into the CSS first, and then the javascript tutorials, -- aaaaand for sure, another glass of wine!
