A markup language is a system for annotating a document with tags that define its structure and presentation. These languages use codes or tags to tell computers how to display and interpret content, making them readable by both humans and machines. A common example is HTML (HyperText Markup Language), which structures webpages.

How it works

Tags: A markup language uses specific tags to mark up a document. For example, in HTML, h1 indicates a heading, and b indicates bold text.

Structure and presentation: The tags define the role and appearance of the content. For instance, a tag might specify that a piece of text is a heading, a paragraph, or a link.

Human-readable: Unlike programming languages, markup languages are typically written using standard words, making them easier for humans to read and write.

Computer interpretation: Software applications, like web browsers, can read these tags and render the document correctly based on the instructions.
