Frequently Asked Questions
What is the CSS box-shadow property? expand_more
box-shadow adds shadow effects around an element. It accepts a horizontal offset, vertical offset, blur radius, spread radius, and color, with an optional inset keyword for inner shadows.
How do I create an inset shadow? expand_more
Enable the "Inset" checkbox in the [Box Shadow Generator](/tools/box-shadow-generator/). This adds the inset keyword so the shadow appears inside the element instead of outside.
What is the difference between blur and spread? expand_more
Blur radius softens the shadow edges (larger = fuzzier). Spread radius grows or shrinks the shadow size before blurring. Negative spread makes the shadow smaller than the element.
Can I control shadow transparency? expand_more
Yes! The opacity slider controls the alpha of the shadow color, output as an rgba() value so shadows blend naturally with any background.
Can I add multiple shadows? expand_more
CSS supports multiple shadows separated by commas. Generate each shadow with the [Box Shadow Generator](/tools/box-shadow-generator/), then combine the values in your stylesheet.
