Frequently Asked Questions

Can I copy the generated CSS directly into my project?

Yes. Every design generator outputs ready-to-paste CSS you can drop straight into a stylesheet or component.

Will the output work across modern browsers?

The generated CSS uses widely supported properties. For very old browser support, double-check vendor prefixes and fallback values for your target audience.

Does changing settings affect performance on my site?

Values like blur, shadow layers, or gradient stops are just CSS — performance impact is minimal and no different from writing the CSS by hand.

Can I save or share a specific design configuration?

Copy the generated CSS or the tool’s URL parameters (where supported) to preserve a specific look for later or to share with a teammate.
