Frequently Asked Questions
Why do professional designers avoid pure black (#000000) shadows?
Pure black shadows at high opacity create unnatural, muddy borders. Tinting your shadow with a low-opacity shade of your brand color (e.g. violet, navy, or slate) mimics natural ambient light bounce and gives interfaces a high-end, cohesive feel.
Can I use this shadow in Tailwind CSS?
Yes. You can paste the generated CSS value into your tailwind.config.js under theme.extend.boxShadow or use an arbitrary class such as shadow-[4px_4px_16px_0px_rgba(124,58,237,0.25)].
Does this support inset shadows?
The core builder focuses on drop elevation (outer shadows), which accounts for 95% of web design requirements. You can add the "inset" keyword directly to the output snippet if an inner well effect is required.
