Getting a box-shadow to look right — soft enough to feel natural, positioned correctly, without being either invisible or overpowering — usually takes several rounds of trial and error directly in code. This tool replaces that guesswork with live sliders you can drag while watching the shadow update in real time.
Adjust horizontal and vertical offset to control the shadow's direction, blur for softness, spread for size, and pick any color including semi-transparent shades for a more subtle effect.
Once it looks right, copy the exact CSS declaration straight into your stylesheet.

Frequently asked questions
What's the difference between blur and spread?
Blur softens the shadow's edges, making it fade out gradually; spread expands or contracts the shadow's overall size before blurring is applied.
Can I create an inset shadow?
This generator focuses on standard drop shadows; for an inset shadow you'd add the word 'inset' to the beginning of the generated CSS value by hand.
