How to use the box shadow generator

  1. Adjust horizontal offset

    Set how far left or right the shadow extends from the element.

  2. Set vertical offset

    Control how far above or below the shadow falls.

  3. Adjust blur radius

    Higher blur values create softer, more diffuse shadows.

  4. Set spread radius

    Positive spread expands the shadow; negative shrinks it.

  5. Copy the CSS

    Once satisfied with the preview, click 'Copy CSS' to get your box-shadow declaration.

What is a box shadow generator?

The Box Shadow Generator creates CSS box-shadow declarations through an interactive visual editor. Adjust horizontal offset, vertical offset, blur radius, spread radius, colour, and opacity in real time — seeing the shadow effect live before copying the CSS code.

CSS box shadows add depth and dimension to UI elements — cards, buttons, modals, and containers. Creating the perfect shadow for your design involves multiple parameters, and getting them right visually is much faster with this interactive tool than adjusting values in a stylesheet.

Why use a box shadow generator?

The perfect box shadow elevates UI design from flat to polished. Instead of tweaking CSS values blindly and refreshing your browser, this tool lets you see the shadow effect update in real time as you adjust parameters — cutting design iteration time dramatically.

Box shadow generator: frequently asked questions

What is box-shadow in CSS?

box-shadow adds shadow effects around an element's frame. Values specify: horizontal-offset vertical-offset blur-radius spread-radius colour. Multiple shadows can be layered with comma separation.

What is an inset shadow?

Adding 'inset' to a box-shadow makes the shadow appear inside the element rather than outside. Inset shadows create pressed, sunken, or inner-glow effects.

How do I create a soft, realistic shadow?

For realistic shadows: use a large blur radius, small spread, low opacity (20-40%), and a slightly warm dark colour (rgba(0,0,0,0.2)) rather than pure black. Multiple stacked shadows create particularly realistic depth.

Can I stack multiple box shadows?

Yes. CSS allows multiple box shadows separated by commas. This tool supports adding multiple shadow layers, useful for creating complex layered shadow effects.

Does box-shadow affect layout?

No. box-shadow doesn't affect the document layout — the shadow is painted without taking up space. It's purely visual and won't push other elements around.
