What Is a CSS Box Shadow?
A CSS box shadow is a visual effect that adds depth to elements like cards, buttons, images, and containers.
At its core, it looks like this:
box-shadow: 0px 10px 20px rgba(0,0,0,0.2);
But those numbers can quickly become confusing:
- Horizontal offset
- Vertical offset
- Blur radius
- Spread
- Color
Getting the perfect shadow manually is tedious.
That’s where a CSS Box Shadow Generator saves hours.
Instead of guessing values, you simply move sliders and instantly see results.
