HTML (HyperText Markup Language) is the standard for creating websites. The idea was proposed in 1989 by physicist Tim Berners-Lee at CERN. Web browsers can read this language to interpret the coding into different texts, colors, formats (headings, paragraphs, quotes, and other semantics), hyperlinks, and can insert images or audio using URL embedding.

Users can see the HTML coding by looking at the “View Source” tab on their browser. Some email programs allow the use of HTML to format the text of a document.
