rehype is a popular free and open source tool that transforms HTML with plugins. Plugins can inspect and change HTML.

• to learn HTML, see MDN
• we follow HTML (the living standard) by WHATWG
• we use parse5 for parsing and hast as the syntax tree
• to find plugins, see rehypejs/awesome-rehype, the list of plugins, and the rehype-plugin topic
