About CSS Box Shadow Generator
This is a visual CSS box-shadow generator. Drag the sliders for horizontal and vertical offset, blur radius, and spread, pick a shadow color, set its opacity, and switch between a normal (outset) or inset shadow. The preview box updates as you change any value, and the exact `box-shadow` CSS is written out below it, ready to copy into your stylesheet.
You can stack multiple shadow layers on one element the same way real designs do - a soft ambient shadow plus a tighter contact shadow, for example - by clicking "Add shadow" and editing each layer independently. All layers are combined into a single comma-separated `box-shadow` rule. You can also change the box color, the preview background, and the corner radius to see how the shadow reads against your actual UI.
The color is emitted as an `rgba()` value so the opacity slider maps directly to the shadow's alpha channel. Everything runs locally in your browser using the same CSS the browser itself renders, so what you see in the preview is what you get - nothing is uploaded and there is no account.
Frequently asked questions
- What do offset, blur, and spread actually do?
- Offset X moves the shadow left/right and Offset Y moves it up/down (positive Y drops it below the box). Blur softens the edge - larger values give a more diffuse shadow. Spread grows (positive) or shrinks (negative) the shadow's size before the blur is applied.
- Can I create layered shadows like the popular design presets?
- Yes. Click 'Add shadow' to stack additional layers, and edit each one separately by selecting its Layer button. All layers are joined into one comma-separated box-shadow rule, which is how designers build realistic multi-step depth.
- What is an inset shadow?
- An inset shadow is drawn inside the element instead of behind it, which makes the box look pressed in or recessed. Switch the Type dropdown to Inset for the selected layer to see it.
- How do I get the code into my project?
- Adjust the sliders until the preview looks right, then click Copy CSS. It copies a complete box-shadow: ...; declaration you can paste directly into a CSS rule or an inline style.
- Is the preview accurate to what browsers render?
- Yes. The preview applies the exact same box-shadow value to a real element, so the browser renders it identically to how your site will. The copied CSS is character-for-character what drives the preview.
- Does this send my data anywhere?
- No. The generator is entirely client-side - all calculations and the preview happen in your browser. There are no uploads, no network calls, and no sign-up.
