HTML (HyperText Markup Language) is the markup language for creating web pages and other information to be displayed in a web browser. Questions regarding HTML should include a minimal reproducible example and some idea of what you're trying to achieve. This tag is rarely used alone and is often paired with [CSS] and [JavaScript].
HTML (HyperText Markup Language) is the markup language used for structuring web pages and other information to be displayed in a web browser. HTML describes the structure of a web page semantically along with cues for presentation, making it a markup language rather than a programming language. A browser 'renders' HTML in conjunction with CSS, which defines the 'style' (colors, fonts, layout, etc.), and JavaScript, which defines interactive and dynamic elements, adding style and behavior to the pages.
https://html.spec.whatwg.org/multipage/ is the canonical HTML specification.
HTML (HyperText Markup Language) is the main markup language for creating web pages and other information to be displayed to humans in a web browser.
It was invented by Sir Tim Berners-Lee while developing the first Web browser at CERN to enable researchers to share their findings and formally released in June 1993. The original "HTML Tags" were first publicly mentioned by Berners-Lee in 1991 and borrowed the syntax from CERN's SGML-based documentation standard. The latest and current version for HTML is HTML5.3.
HTML elements form the building blocks of all web pages. HTML allows images and objects to be embedded in a page. It references styles and scripts and carries meta-data. It can be used to create interactive forms. It provides a means to create structured documents by denoting structural semantics for text such as headings, paragraphs, lists, links, quotes, and other items. It can embed scripts written in languages such as JavaScript, which affects the behavior of HTML web pages. Web pages written in different programming languages (PHP, JSP, VF, ASP.NET, etc.) get rendered as HTML in a browser.
HTML is a hierarchical (tree-structured) markup language. That is, an item might be a descendant of another item, which is its ancestor. However, if item2 is a descendant of item1, then they have an additional special relation: item2 is inside of item1, or item1 is wrapped around item2.
Syntax
HTML is written in the form of elements consisting of tags (and their attributes) enclosed in angle brackets (e.g., <html>
).
HTML tags most commonly come in pairs. The first is known as the opening tag and the second, which includes a forward slash, as the closing tag (e.g., <h1>
and </h1>
). Various types of content, such as text or additional HTML elements, can be contained within these tags. Some tags, however, are unpaired, and these are known as empty elements or self-closing tags. They may or may not include the slash (e.g., <img>
or <img />
).
Collectively, these tags form an HTML document. Web browsers read these documents, interpret each of the HTML tags, and then render their corresponding visual and/or audible display in the form of a webpage.
Standards
HTML standards, as well as those for many other web technologies, are maintained by the World Wide Web Consortium (W3C).
HTML4 was introduced in 1997, and the latest iteration, HTML5, was recently developed by the W3C. What W3C calls HTML5 is a subset, with a few modifications, of the HTML-Living-Standard which is specified by the Web Hypertext Application Technology Working Group (WHATWG).
The language specification and standards documents for HTML5 are available online.
Design and Scripting
HTML markups are designed, or 'styled', via CSS (Cascading Style Sheets), using one or more of the following:
- the
<link>
tag, loading a CSS file - the
<style>
tag, where CSS rules are defined - the
style
attribute of HTML tags, where inline styles can be specified
Dynamic and interactive parts of a page are programmed most frequently via JavaScript, using one or more of the following:
- the
<script>
tag with ansrc
attribute pointing to the path of a script file - the
<script>
tag with its inner text being the script - event attributes of tags, like
onclick
