HTML[1] elements constitute the fundamental units of HTML web pages. They represent individual parts that constitute an HTML document, imparting significance and organization to the content. Every element can possess distinct attributes and can encompass other elements and text. These elements are organized in a hierarchical tree structure within an HTML document. While the majority of elements necessitate both opening and closing tags, some, referred to as void elements, do not require closing tags. The proper arrangement and nesting of these elements are vital for generating valid HTML documents. HTML elements can be classified into three categories: normal, raw text, and void elements. The usage of upper or lower case in writing these elements can vary. It’s also crucial to acknowledge that some elements have been phased out or considered invalid in subsequent standards due to considerations such as user accessibility.
Un Élément HTML est un type de HTML (HyperText Markup Language) document component, one of several types of HTML nodes (there are also text nodes, comment nodes and others).[vague] 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 of simple HTML nodes, such as text nodes, and HTML elements, which add sémantique and formatting to parts of document (e.g., make text bold, organize it into paragraphs, lists and tables, or embed hyperlinks and images). Each element can have HTML attributes specified. Elements can also have content, including other elements and text.
