Frequently Asked Questions
What are the box-shadow values?
box-shadow takes: horizontal-offset vertical-offset blur-radius spread-radius color. Positive horizontal moves right, positive vertical moves down. Blur softens the shadow. Spread expands it. The optional inset keyword makes it an inner shadow.
What does "inset" do in box-shadow?
The inset keyword turns the shadow from an outer drop shadow into an inner shadow that appears inside the element. Inner shadows are useful for creating pressed/sunken button effects, input field depth, and embossed designs.
Can I add multiple shadow layers?
Yes — CSS box-shadow accepts multiple comma-separated values. Each layer adds depth. Stacking a tight hard shadow with a larger soft shadow creates realistic elevation effects like Material Design cards.
What is the difference between blur and spread?
Blur determines how soft/fuzzy the shadow edges are (0 = hard sharp edge). Spread expands or contracts the shadow before blurring — positive spread makes the shadow larger than the element, negative shrinks it.
