Code Beautify HTML Formatter

This tool formats HTML and embedded code by applying deterministic indentation, consistent attribute wrapping, and standardized line breaks. It preserves comments, CDATA sections, DOCTYPE, and other non-content markers, ensuring the output stays faithful to the original structure while improving readability and maintainability.
Conceptually, it parses the document into a tree, normalizes spacing, and re-serializes with a uniform style. It handles inline CSS and JavaScript blocks, whitespace in void elements, and multi-line attributes. When enabled, attributes can be wrapped to a maximum line width, and empty elements can be expanded or collapsed according to rules, without altering semantics.
Audience and value: front-end developers, UI engineers, template authors, reviewers, and documentation teams gain faster reviews and consistent markup across repositories. Differentiators include deterministic formatting for every run, configurable indent size (2 or 4 spaces or tabs), and safe handling of edge cases like irregular nesting, comments inside attributes, and mixed language blocks. Use cases include preparing HTML for pull requests, publishing templates, and integrating formatting into CI workflows. The tool adheres to HTML5 standards, UTF-8 encoding, and line-ending normalization. It supports integration with CI/CD and code editors by exposing a deterministic formatter that yields identical results for identical inputs, enabling reliable diffs, reviews, and documentation across teams.
