How do I create a glassmorphism or soft shadow effect?
Soft, premium shadows are achieved by using multiple shadow layers, high blur radii, and low opacity colors (like semi-transparent black or dark blue). You can adjust these settings easily using the interactive sliders.
What is the difference between inset and outset box shadows?
An outset shadow is rendered outside the element's border, making it appear elevated. An inset shadow is rendered inside the border, making the element look pressed or sunken into the background.
Does this generator support multiple shadow layers?
Yes, you can add and stack multiple shadow layers to create complex, realistic, and smooth shadows (often called shadow diffusion or layered shadows) that look much more premium than a single-layer shadow.
How do I use the generated CSS in my project?
Simply customize the shadow parameters using the visual sliders, and click the "Copy" button. The tool copies the exact box-shadow CSS property to your clipboard.
