Frequently Asked Questions

What's the difference between beautifying and minifying CSS?

Beautifying formats CSS for readability with proper indentation and spacing. Minifying removes all unnecessary whitespace and comments to reduce file size for production use.

Does this tool support SCSS or Less?

This tool is designed for standard CSS. While it may work with some SCSS/Less syntax, it's optimized for CSS. Use dedicated preprocessor tools for SCSS/Less files.

How much can minification reduce CSS file size?

Typically 20-40% reduction in file size, depending on the original formatting and comment density. Well-formatted CSS with many comments can see even greater reductions.

Are there any limitations to the CSS parser?

This is a lightweight parser for basic CSS validation and formatting. For advanced CSS features or complex syntax, consider using dedicated development tools or linters.

Can I use this tool for large CSS files?

Yes, but very large files may take longer to process. The tool handles files up to several MB, but for enterprise-scale CSS, consider using build tools like PostCSS or Sass.

Is my CSS code safe when using this tool?

Yes, all processing happens in your browser. Your CSS code is never sent to any server, ensuring complete privacy and security of your stylesheets.

Can I use this tool with CSS frameworks?

Yes, the tool works with CSS from any framework (Bootstrap, Tailwind, etc.). However, be careful with minification as it may affect utility classes or specific formatting requirements.

What's the best indentation setting for CSS?

Most developers prefer 2 spaces for CSS indentation as it's cleaner and takes less space. Some teams use 4 spaces for consistency with other languages. Choose based on your team's coding standards.
