While writing box-shadow: 10px 10px 5px rgba(0,0,0,0.5); by hand is possible, fine-tuning the blur radius, spread, and exact alpha-opacity requires constant context-switching between your CSS file and the browser.
Our CSS Box Shadow Generator provides a high-fidelity visual interface to construct the perfect shadow, giving you instantly copyable CSS code.
box-shadowA standard CSS box shadow contains 5 primary values:
0 creates a harsh, solid block of color. Higher values create soft, feathered edges.Modern web design (like Glassmorphism or Neumorphism) rarely relies on a single harsh shadow. Instead, designers layer 2, 3, or even 4 incredibly soft, low-opacity shadows on top of each other to create hyper-realistic depth.
Our generator supports infinite layers. Use the "Add Layer" button to stack shadows and build professional-grade UI elements.
Box-shadow applies shadows to the bounding box of an element. CSS filter: drop-shadow applies shadows to the actual visible contours of shapes, including transparent PNGs and SVGs.
Combine a large blur radius (e.g., 30px) with a very low opacity black or primary accent color, layered on a semi-transparent background.
Yes, you can define multiple comma-separated shadow values on a single element to create photorealistic, smooth lighting effects.
