A CSS shadow generator lets you preview in real time and copy the code by dragging sliders, helping you quickly build visual hierarchy in your portfolio. The core approach is to stack two or three layers of shadow: one large and faint for ambient light, one small and dark for contact shadow, using dark blue or dark gray at 10% to 20% opacity, with a large blur radius and a small or even negative spread radius for crisper edges. Hero cards, thumbnails, sticky navs, and modals are common use cases, but shadow character should stay consistent across the same page. To judge if it's overdone, squint and see whether the shadow steals attention from the content.
