About semantics

Semantics is the study of the relationships between signs and symbols and what they represent. In linguistics, this is primarily the study of the meaning of signs (such as words, phrases, or sounds) in language. In the context of front-end web development, semantics are largely concerned with the agreed meaning of HTML elements, attributes, and attribute values (including extensions like Microdata). These agreed semantics, which are usually formalised in specifications, can be used to help programmes (and subsequently humans) better understand aspects of the information on a website. However, even after formalisation, the semantics of elements, attributes, and attribute values are subject to adaptation and co-option by developers. This can lead to subsequent modifications of the formally agreed semantics (and is an HTML design principle).
