Is incorrect use of HTML explained by lack of education?
Up to the late 1990’s, good HTML education material (guides, references, tutorials, etc.) was hard to come by. If you were a Web developer/designer, you had to use the HTML specification document, which was written for tool vendors. So in the early days of the Web, lack of education could explain some of the incorrect use of HTML. Yet today there is an abundance of good quality education material, and still the new generation of Web designers/developers are just as ignorant of the correct use of HTML as their predecessors.
