❓ Frequently Asked Questions
Can I add multiple drop shadows to one element?
Yes! CSS allows you to comma-separate multiple shadow values. You can easily add and stack multiple shadow layers together in our generator to create complex 3D or glowing effects.
What does the 'spread' value do?
The spread radius expands or contracts the shadow size beyond the element's actual borders before the blur is applied. A positive spread makes the shadow larger, while a negative spread makes it smaller than the element itself.
Is the generated CSS cross-browser compatible?
Absolutely. The `box-shadow` property is universally supported across all modern browsers, including Chrome, Firefox, Safari, and Edge. We generate clean, standard CSS.
Does the Box Shadow Generator work offline?
Yes, the Box Shadow Generator is fully functional offline. Because this tool runs entirely in your browser, no data is ever uploaded to external servers. Once the page is loaded, you can seamlessly continue using it without an active internet connection. You can also install Knicknaks as a Progressive Web App (PWA) for native-like offline access.
