What Is a HTML Formatter?

When you've copied HTML out of a templating engine, scraped a page with a single-line render, or saved a server-side framework output, formatted HTML is what you need before you can read or modify it. The formatter walks the tag stream, increases indentation on opening tags and decreases on closing tags, and leaves text content intact between them.

It knows the HTML void elements (`<img>`, `<br>`, `<input>`, `<meta>`, `<link>`, `<hr>`) so they don't push the indent and don't expect a closing tag. Inline `<script>` and `<style>` blocks pass through without reformatting — use the JavaScript and CSS formatters separately on those blocks if you need them tidied too.

Frequently Asked Questions

Why format HTML?
Formatted HTML is easier to read, debug, and maintain. Proper indentation shows the document structure and nesting of elements.
Does it fix invalid HTML?
No — the formatter focuses on whitespace and indentation. Use an HTML validator for structural issues.
Can I format HTML with inline CSS/JS?
Yes, formatters preserve the content. Inline styles and scripts stay intact — only the structure and indentation are adjusted.
