box-shadow: 0px 8px 24px 0px #00000033;
Craft realistic CSS box-shadow effects without writing the syntax by hand. Tune offset, blur, spread, color and the inset flag — copy the production-ready declaration with one click.
How to generate a CSS box-shadow
- Slide the X and Y offset to position the shadow.
- Increase blur and spread until the shadow feels natural.
- Pick a shadow color and opacity — darker is rarely better.
- Copy the CSS and paste it into your component styles.
Frequently asked questions
Can I stack multiple shadows?+
Yes. CSS allows comma-separated shadow lists. Generate each shadow here, then concatenate them in your stylesheet.
What is the difference between inset and outset?+
Outset shadows render outside the element edge. Inset shadows render inside — useful for pressed buttons, wells and inputs.
Will box-shadow hurt performance?+
Static shadows are essentially free. Avoid animating blur or spread on hover — animate transform or opacity instead.
