CodeMirror is a JavaScript library that can be used to create a relatively pleasant editor interface for code-like content ― computer programs, HTML markup, and similar. If a mode has been written for the language you are editing, the code will be coloured, and the editor will optionally help you with indentation.

Based on CodeMirror.js library by Marijn Haverbeke.

CodeMirror provides many languages for markup and themes for styling.
