About CSS Box Shadow Generator
Elevate your web design workflow with the CSS Box Shadow Generator, a sleek, browser-based tool crafted for frontend developers, UI/UX designers, and web enthusiasts. Stop guessing CSS values and start crafting pixel-perfect, modern shadows visually in real-time. Whether you need a subtle, soft glow for a card component or a bold, dramatic drop shadow for a hero element, this tool gives you complete creative control. Unlike basic generators, this tool offers granular, intuitive sliders for every critical shadow property: Offset X, Offset Y, Blur Radius, and Spread Radius. Easily fine-tune the aesthetic with a built-in color picker, and instantly toggle between standard outer shadows and elegant inset (inner) shadows. The live preview updates with zero latency, ensuring exactly what you see is what you get. Designed with a beautiful, modern glassmorphism interface, the tool features a dedicated code output panel with a one-click "Copy" button and a sleek toast notification for seamless workflow integration. A "Remove default shadow" toggle lets you isolate your custom shadow for precise evaluation. Best of all, it is 100% client-side. All processing happens locally in your browser, meaning zero lag, no external dependencies, and absolute privacy for your design process. Fast, intuitive, and production-ready.
How to use CSS Box Shadow Generator
- Use the Offset X and Offset Y sliders to position the shadow horizontally and vertically relative to the box.
- Adjust the Blur slider to soften the shadow's edges (higher values = softer, more diffused shadows).
- Tweak the Spread slider to expand (positive values) or contract (negative values) the shadow's overall size before the blur is applied.
- Click the color swatch to open the native color picker and choose the perfect shadow hue.
- Check the "Inset shadow" box to flip the shadow inside the element for a pressed or recessed effect.
- Toggle "Remove default shadow" to hide the preview box's baseline shadow and see only your generated effect.
- Click the "Copy" button to instantly copy the generated CSS code to your clipboard.
- Hit the "Reset" button (or press the R key on your keyboard) to revert all sliders to their default starting positions.
Frequently asked questions
Is this tool free and private?
Yes, it is 100% free to use. All calculations and preview rendering happen locally in your browser, meaning no data is ever sent to external servers.
What is the difference between "Blur" and "Spread"?
Blur determines how soft or fuzzy the edges of the shadow are. Spread determines the actual size of the shadow, making it larger or smaller before the blur effect is applied.
Can I create inner shadows with this tool?
Absolutely. Simply check the "Inset shadow" checkbox, and the generator will add the inset keyword to your CSS, pushing the shadow inside the element.
Why is there a "Remove default shadow" checkbox?
The preview box has a subtle default shadow to make it visible against the background. Checking this box removes it, allowing you to evaluate your custom shadow in complete isolation.
How do I quickly reset all the settings?
You can click the "Reset" button at the bottom of the controls panel, or simply press the R key on your keyboard (as long as you aren't actively typing in an input field).
Does the tool support transparent shadows?
The color picker outputs standard Hex codes. If you need transparency, you can easily copy the generated code and manually change the Hex value to an rgba() or hsla() value in your own CSS editor.
Is the interface mobile-friendly?
Yes, the tool features a fully responsive grid layout that adapts seamlessly to smartphones, tablets, and desktop monitors.
Can I generate multiple shadows for one element?
This tool is optimized for generating a single, clean box-shadow declaration. For complex, multi-layered shadows, you can generate two separate shadows and combine them in your CSS using a comma.
