How do I convert a CSS file to RB?

Upload your CSS file or paste its content into the converter. Choose RB as the target format, then click 'Convert'. The tool will parse the CSS syntax and generate a Ruby file that retains all selectors, properties, and media queries. Download the result or copy it to your clipboard.

Why would I need to convert CSS to Ruby (RB)?

This conversion is essential for Ruby on Rails developers who prefer to define styles programmatically or integrate with server-side rendering. By converting CSS to RB, you can manage style objects like regular Ruby data, making them easier to test, reuse, and version control. It also enables dynamic style generation based on user roles or device conditions.

How does the conversion handle CSS media queries and vendor prefixes?

Media queries are translated into Ruby 'case/when' blocks that evaluate the same browser width, orientation, or feature conditions. Vendor prefixes like -webkit- are preserved as plain strings within property keys, so no compatibility data is lost. The cascade order is maintained by the sequence of hashes in the output array, and any comments become Ruby comments. Invalid CSS syntax is listed in the conversion log.

Is CSS-TO-RB free to use?

Yes, CSS-TO-RB on LetsConvert is 100% free with no registration or hidden fees required.

Are my uploaded files safe and secure?

Yes! File privacy and security are guaranteed. Basic conversions run locally in your browser. Files sent for server processing are automatically deleted within 1 hour.

Does this converter work on mobile phones and tablets?

Yes! CSS-TO-RB works seamlessly across iPhone, Android, iPad, Mac, Windows, and Linux browsers without installing any app.

Is there any software installation required?

No software or browser extension installation is needed. All conversions are performed directly online.
