What the HTML beautifier does
It parses your markup with Prettier and reprints it with nested indentation, so deeply structured pages and components become easy to read and edit.
Why beautify HTML
Server-rendered or minified HTML is often one long line. Beautifying reveals the DOM structure so you can find and change elements confidently.
Handles inline CSS and JS
Prettier formats embedded style and script blocks too, keeping your whole document consistent.
