HTML defaults

What will be an ideal response?

It is vital that students appreciate the concept that HTML exists complete and
apart from CSS. HTML elements possess built-in formatting that frequently must
be overridden by CSS. This exercise describes how HTML default formatting can
affect web design.
HTML5 has broken from this concept of default formatting. At the time of this
writing, there was no default style sheet for HTML5 elements. This means in the
future HTML elements may not exhibit any intrinsic formatting at all. For the
time being, browser vendors are continuing to support the default style sheet for
HTML 4.01, even for pages using HTML5 code and structures. Students should not
assume that HTML will always display such default styles in the future.
