Does this HTML and CSS formatter send my code to a server?

No. All formatting, beautification, and minification runs 100% locally in your browser using pure client-side JavaScript. Your code never leaves your device.

Does it format CSS and JavaScript inside HTML documents?

Yes. When beautifying HTML documents containing and blocks, the formatter preserves and neatly indents the internal CSS rulesets and scripts.

Can I sort CSS properties alphabetically?

Yes, toggle the 'Sort Properties' checkbox to automatically order declarations within every CSS selector block alphabetically for consistency.

Frequently Asked Questions

How does the auto-detect syntax feature determine HTML vs. CSS?

The parser scans the leading content for HTML document signatures like <!DOCTYPE, opening tags (<div>, <html>), and XML tags. If none are found, or if curly-brace declaration blocks { ... } predominate, it selects CSS formatting automatically.

Does the minifier break inline scripts or CSS styles?

No. Our minifier safely processes standard markup while preserving string literals, regular expression delimiters, and essential CSS spacing such as calc() expressions.

Are self-closing void elements handled correctly according to HTML5 standards?

Yes. Standard HTML5 void tags (such as <img>, <br>, <input>, <meta>, <link>, <hr>) do not require a closing slash and do not increase the indentation depth of sibling elements.
