Alkane Code is a user-friendly, lightweight code editor for TinyMCE that adds ‘language-‘ classes to HTML code elements. It can be used to add inline code as well as block code, and syntax highlighting at the front-end is performed using Prism.js with auto-loaded languages. It does not support the Gutenberg editor. You will need to install the ‘Classic Editor’ plugin to use this code editor.
