Stop guessing CSS pixel values. Visually design complex, multi-layered box shadows with real-time feedback. Includes support for inset shadows, alpha-transparency, and dark-mode previewing.
box-shadow:10px 10px 25px -5px rgba(0, 0, 0, 0.25);
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.
The `box-shadow` CSS property adds shadow effects around an element's frame. You can set multiple effects separated by commas. A box shadow is described by X and Y offsets relative to the element, blur and spread radius, and color.
Neumorphism typically requires multiple box shadows on the same element: one light shadow on the top-left (negative X/Y offset) and one dark shadow on the bottom-right (positive X/Y offset), matching the background color closely.
An inset shadow draws the shadow inside the frame of the element rather than outside it, making the element look like it is pressed into the page. You can enable this by toggling the 'Inset' switch.
