An '''HTML element''' is a type of [[HTML]] (HyperText Markup Language) document component, one of several types of HTML nodes (there are also text nodes, comment nodes and others).{{Vague|date=February 2019}} The first used version of HTML was written by [[Tim Berners-Lee]] in 1993 and there have since been many versions of HTML. The current de facto standard is governed by the industry group [[WHATWG]] and is known as the HTML Living Standard.

An HTML document is composed of a [[tree structure|tree]] of simple HTML [[Node (computer science)|nodes]], such as text nodes, and HTML elements, which add [[semantics]] and formatting to parts of a document (e.g., make text bold, organize it into paragraphs, lists and tables, or embed [[hyperlink]]s and images). Each element can have [[HTML attribute]]s specified. Elements can also have content, including other elements and text.

====Phrase elements====

Phrase elements are used for marking up phrases and adding structure or semantic meaning to text fragments. For example, the <code><nowiki><{{tag|em></nowiki></code>|o}} and <code><nowiki><{{tag|strong></nowiki></code>|o}} tags can be used for adding emphasis to text.
