What is the difference between a drop shadow and an inset shadow?

A drop shadow (default) appears outside the element, making it look as though it is floating above the background. An inset shadow appears inside the element, creating a 'punched-in' or recessed effect, commonly used for inner-glows or active button states.

How do I create a really soft, realistic shadow?

Professional designers rarely use one shadow. The secret is layering. Start with a sharp, dark shadow with low blur for a core depth, then add a second, wider layer with high blur and very low opacity (5-10%) to simulate ambient light scattering.

Does the order of shadow layers matter?

Yes, in CSS, the first shadow in the list is rendered on top (closest to the user), and subsequent shadows are rendered behind it. Our manager allows you to toggle layers so you can see the impact of each.

Are CSS shadows better than using image assets?

Significantly. CSS shadows are vector-based, meaning they are perfectly crisp at any resolution and take up almost zero bandwidth. They are also dynamic, allowing you to animate them on hover or interaction using CSS transitions.

Is box-shadow compatible with all browsers?

Yes, the `box-shadow` property is a core part of CSS3 and is supported by effectively 100% of modern browsers. No vendor prefixes are required for standard evergreen browsers today.

What does the 'Spread' property do?

The spread radius allows you to expand or contract the size of the shadow. A positive value makes the shadow larger than the element, while a negative value makes it smaller—useful for creating specialized 'directional' shadows.

Box Shadow Generator

Box Shadow Generator Overview

Create CSS box shadows visually

The CSS Box Shadow Generator is a professional-grade visual editor designed for web developers and designers who want to create sophisticated, high-performance shadow effects without the trial-and-error of manual coding. Box shadows are a fundamental element of modern UI design, used to create depth, elevation, and hierarchy in digital interfaces. However, the `box-shadow` property syntax—especially for complex multi-layer or inset shadows—can be challenging to visualize and fine-tune manually. Our generator provides a real-time, interactive environment where you can layer multiple shadows, adjust their offsets, blur, and spread with pixel-perfect precision. Great UI design often relies on 'soft' shadows that mimic natural lighting. By using our multi-layer support, you can stack several shadows with varying opacities and blur levels to achieve much more realistic and pleasing results than a single, high-contrast shadow. Whether you're designing a subtle card component, a prominent call-to-action button, or a complex 'glassmorphism' effect, this tool gives you full control over the alpha transparency and positioning needed for professional results. Every shadow you generate is processed entirely on the client side, ensuring your data remains private and the interface stays lightning-fast. The tool outputs clean, standard-compliant CSS code that is compatible with all modern browsers including Chrome, Safari, Firefox, and Edge. Elevate your web design project instantly with mathematically perfect shadows generated in seconds.

How to Use Box Shadow Generator

**Define Base Layers**: Use the 'Add Layer' button to stack multiple shadows for a more realistic, soft depth effect.
**Adjust Offsets**: Use the X and Y sliders to move the shadow horizontally or vertically relative to the element.
**Control Diffusion**: Increase the **Blur Radius** for a softer, wider shadow, or decrease it for a sharper edge.
**Set Volume**: Use the **Spread** slider to increase or decrease the size of the shadow relative to the box.
**Pick Color & Opacity**: Choose any hue and adjust the alpha transparency to match your interface's theme.
**Toggle Inset**: Use the Inset switch to swap between a drop shadow (outside) and an inner shadow (inside).
**Copy and Paste**: Click the CSS code block to copy the `box-shadow` property directly to your stylesheet.
