Introduction to markup languages
If you need an intro/introduction to any of the following markup languages HTML, XML, Markdown, MathML, SVG, XHTML, please watch my videos on my YouTube playlist “Introduction to markup languages”.
Introduction to HTML
The HyperText Markup Language or HTML is the standard markup language for documents designed to be displayed in a web browser.
It can be assisted by technologies such as Cascading Style Sheets (CSS) and scripting languages such as JavaScript.
Web browsers receive HTML documents from a web server or from local storage and render the documents into multimedia web pages.
HTML describes the structure of a web page semantically and originally included cues for the appearance of the document.
HTML elements are the building blocks of HTML pages.
With HTML constructs, images and other objects such as interactive forms may be embedded into the rendered page.
HTML provides a means to create structured documents by denoting structural semantics for text such as headings, paragraphs, lists, links, quotes and other items.
HTML elements are delineated by tags, written using angle brackets.

Introduction to XML
Extensible Markup Language (XML) is a markup language and file format for storing, transmitting, and reconstructing arbitrary data.
It defines a set of rules for encoding documents in a format that is both human-readable and machine-readable.
The World Wide Web Consortium’s XML 1.0 Specification of 1998 and several other related specifications — all of them free open standards — define XML.
The design goals of XML emphasize simplicity, generality, and usability across the Internet.
It is a textual data format with strong support via Unicode for different human languages.
Although the design of XML focuses on documents, the language is widely used for the representation of arbitrary data structures such as those used in web services.
Several schema systems exist to aid in the definition of XML-based languages, while programmers have developed many application programming interfaces (APIs) to aid the processing of XML data.
The main purpose of XML is serialization, i.e. storing, transmitting, and reconstructing arbitrary data.

Introduction to Markdown
Markdown is a lightweight markup language for creating formatted text using a plain-text editor.
John Gruber and Aaron Swartz created Markdown in 2004 as a markup language that is appealing to human readers in its source code form.
Markdown is widely used in blogging, instant messaging, online forums, collaborative software, documentation pages, and readme files.
The initial description of Markdown contained ambiguities and raised unanswered questions, causing implementations to both intentionally and accidentally diverge from the original version.
This was addressed in 2014, when long-standing Markdown contributors released CommonMark, an unambiguous specification and test suite for Markdown.
Markdown was inspired by pre-existing conventions for marking up plain text in email and usenet posts, such as the earlier markup languages setext (c. 1992), Textile (c. 2002), and reStructuredText (c. 2002).
