Lecture notes for Week Eight (MGDP2050).

HTML and semantics

In principle, the role of HTML is to provide semantics (meaning).

In practice, HTML is a mix of semantic and non-semantic elements.

Semantic HTML

Semantic HTML refers to HTML that is entirely semantic (or perhaps "very semantic with acceptable compromises").

Bold versus strong

Earlier versions of HTML specified a bold element, to make text display in boldface.

HTML 4 also specified a strong element, intended to replace the bold element.

Both elements are valid in HTML5.

Italic versus emphasis

Earlier versions of HTML specified an italic element, to make text display in italicf.

HTML 4 also specified an emphasis element, intended to replace the italic element.

Both elements are valid in HTML5.
