Frequently asked questions
How does the CSS box-shadow property work?
The box-shadow property takes values for horizontal offset, vertical offset, blur radius, spread radius, and color. It applies one or more drop shadows to an element's frame.
What is the difference between blur radius and spread radius?
Blur radius softens and expands the shadow edges so they fade out gradually. Spread radius increases or decreases the overall size of the shadow shape before the blur is calculated.
What does the inset keyword do?
Adding inset changes the shadow from an outer drop shadow to an inner shadow drawn inside the element's border box.
Does the generated code require browser prefixes?
No, modern browsers fully support standard box-shadow syntax without vendor prefixes like -webkit- or -moz-.
Is this CSS box shadow generator free?
Yes, this tool is completely free to use online with no signup or software installation required.
