Questions

How do I add a box shadow in CSS?
Use the visual editor to set the horizontal offset, vertical offset, blur radius, spread radius, and shadow color. The tool generates the ready-to-use CSS box-shadow property value that you can paste into your stylesheet.
Can I add multiple box shadows to one element?
Yes, CSS supports multiple comma-separated box-shadow values on a single element. You can layer shadows to create effects like glows, insets, and realistic depth by combining several shadow definitions.
What is an inset box shadow?
An inset box shadow renders inside the element instead of outside, creating an inner shadow or pressed-in effect. Add the inset keyword before the offset values in the box-shadow property.
Does the box shadow generator affect page performance?
Box shadows are GPU-accelerated in modern browsers and have minimal performance impact. Very large blur values on many elements can slow rendering, but typical usage is fine.
Is the box shadow generator private and safe to use?
All shadow calculations run in your browser. No data is sent to any server, so your design choices remain completely private.
