Frequently asked questions

What shadow types are supported?
Box shadows (for elements) and text shadows (for text). Both support offset X/Y, blur radius, color and alpha. Box shadows also include spread radius.
Is the output production-ready?
Yes — the CSS uses standard rgba() color notation and is ready to paste into any stylesheet. It works in all modern browsers.
Can I create layered shadows?
This tool generates single shadows. For layered effects, generate multiple shadows and combine them with commas in your CSS.
