How CSS Formatters Work

At its core, a CSS Formatter follows parsing rules to tokenize and reconstruct your stylesheets. Here’s a basic workflow:

Input Parsing – CSS code is scanned and broken down into selectors, properties, and values.
Syntax Tree Construction – The parsed tokens are structured into a logical syntax tree.
Formatting Rules Application – Rules like indentation size, spacing between selectors, and line break preferences are applied.
Output Generation – The beautified code is output, maintaining syntactic integrity and developer preferences.
