The <code> tag is used to insert fragments of program code, variables, etc. into an HTML document. In the browser, the code is displayed in a monospaced font (a font in which all characters are of the same width) of the smaller size.
The <code> tag comes in pairs. The content is written between the opening (<code>) and the closing (</code>) tags.
<html> <head> <title>Title of the document</title> </head> <body> <p>Ordinary text.</p> <code>Line of program code.</code> <p>Continuation of the ordinary text.</p> </body> </html>
