Markup language
The markup language is a text-encoding system which specifies the structure and formatting of a document and potentially the relationships among its parts. Markup can control the display of a document or enrich its content to facilitate automated processing. There are various types of markup languages, such as HTML, KML/KMZ, XML, Markdown, and others.
Due to its simplicity and popularity it is recommended to use Markdown. Furthermore, since it is often possible to combine Markdown with HTML, it is possible to use the CSS to style the text. It is recommended to use a CSS framework like Tailwind CSS.
