Would you, as a handcoder, leave that invalid parts in code? No? So where's the problem to fix the missing bits from Dreamweaver then? Turn on W3C validation, open the file in the editor part of Dreamweaver, and fix it message by message. Done.
My point is that even with invalid code parts i am ways faster to clean it up than to write the whole stuff from scratch.
And my point is that it makes no sense to learn html when you just want to make one or two non-professional hobby pages in your life
To fix a misunderstanding here. I have nothing against hand coding. But it is not the only valid way to reach the goal to create a webpage nowadays.
