Designing CSS Box Shadows Visually
Overview
A box-shadow generator lets you craft the CSS box-shadow property by dragging sliders instead of guessing numbers. Shadows add depth and hierarchy to buttons, cards, and modals, but the syntax — offsets, blur, spread, color, and inset — is fiddly to write by hand. This tool shows a live preview as you adjust each value and gives you the exact CSS to copy, all in your browser.
How to Use (Step by Step)
- 1
Adjust the sliders
Set the horizontal and vertical offset, blur, spread, and color while watching the live preview.
- 2
Stack shadows if needed
Add multiple shadow layers for depth, or switch on inset for an inner shadow.
- 3
Copy the CSS
Grab the generated box-shadow value and paste it into your stylesheet or component.
How It Works
The box-shadow property takes horizontal and vertical offsets, a blur radius, an optional spread, and a color (usually with transparency). You move sliders for each and the preview updates instantly, so you can see exactly how the shadow falls. The tool writes the matching box-shadow declaration, including multiple stacked shadows if you add them, ready to paste into your stylesheet.
When to Use This
Adding a subtle shadow to lift a card or button off the page. Matching a shadow from a design mockup without eyeballing the values. Building a layered, realistic shadow with multiple stacked layers. Creating an inset shadow for pressed or inset UI elements. Fine-tuning shadow softness and color for dark or light themes. Learning how each box-shadow value affects the result.
Frequently Asked Questions
In order: horizontal offset, vertical offset, blur radius, and spread. Offsets move the shadow, blur softens its edge, and spread grows or shrinks it. A color follows, often rgba() with low opacity for subtlety.
Important Notes
Heavy or numerous box-shadows can hurt rendering performance, especially when animated. Keep shadows subtle and limit stacked layers on elements that move or update frequently.
