About CSS box shadow generator

The CSS box-shadow property adds drop shadows to HTML elements and is one of the most commonly tweaked properties in UI design. Getting the right combination of horizontal offset, vertical offset, blur radius, spread radius, colour, and opacity by hand is slow and iterative. The CSS Box Shadow Generator provides sliders and a colour picker with a live preview box so you can dial in the exact shadow you need visually, then copy the ready-to-paste CSS value. Multiple shadows can be layered on a single element for more complex lighting effects.
