Frequently Asked Questions

What is a CSS formatter and why should I use it? A CSS formatter is an essential tool that automatically beautifies and organizes your stylesheets for better readability and maintenance. It ensures consistent code style across your team, reduces syntax errors, and makes debugging much easier. Our formatter supports multiple indentation styles, instant minification for production, and smart vendor prefix management - saving hours of manual work. How does the CSS autoprefixer feature work? Our autoprefixer analyzes your CSS properties and automatically adds vendor prefixes like -webkit-, -moz-, and -ms- based on real browser usage statistics. You can choose coverage targets such as "last 2 versions" for modern browsers or ">1% usage" for broader support. This eliminates the need to manually track browser compatibility and ensures your styles work across all targeted browsers. Can I convert SASS or LESS to CSS online? Absolutely! Simply paste your SASS/SCSS or LESS code and click the respective conversion button. Our tool handles all preprocessor features including variables, nesting, mixins, functions, and imports. The conversion happens instantly in your browser, producing clean, optimized CSS that's ready for production use. What's the difference between formatting and minifying CSS? Formatting (beautifying) makes your CSS human-readable with proper indentation, line breaks, and spacing - perfect for development and debugging. Minifying does the opposite: it removes all unnecessary characters to create the smallest possible file size for production. Our tool shows real-time compression ratios, typically achieving 20-50% size reduction. How does CSS validation work in this tool? Our validator checks your CSS in real-time for syntax errors, invalid properties, malformed selectors, and potential browser compatibility issues. The status bar provides instant feedback with specific error messages, helping you catch and fix problems before they reach production. Valid CSS shows a green checkmark for peace of mind. Can I sort CSS properties and why would I want to? Yes! Property sorting improves code consistency and readability. Sort alphabetically for easy property lookup, or use logical grouping (positioning → box model → typography → visual) for better organization. Consistent property order reduces merge conflicts in version control and helps teams maintain coding standards. Is my CSS code secure when using this formatter? Your code security is our top priority. All CSS processing happens locally in your browser using JavaScript - your code never leaves your device or gets uploaded to any server. This client-side approach ensures complete privacy for proprietary stylesheets while providing instant, offline-capable formatting. What browsers and CSS versions are supported? Our formatter supports all modern browsers (Chrome, Firefox, Safari, Edge) and handles CSS3, CSS4, and experimental features. The tool processes standard CSS plus SASS/SCSS and LESS syntax. File size limit is 2MB, which accommodates even the largest production stylesheets. Mobile devices are fully supported with an optimized responsive interface.
