Frequently Asked Questions

What is a Box Shadow Generator?+

A Box Shadow Generator is a free online tool that helps you visually create CSS box-shadow values and instantly copy the generated CSS code. It provides real-time preview of shadow effects with adjustable parameters like offset, blur, spread, color, and opacity, making it easy for web designers and developers to create perfect shadows without manual coding.

Is the Box Shadow Generator free to use?+

Yes, the Box Shadow Generator is completely free and works directly in your browser without requiring any sign-up, registration, or payment. All features are available immediately with no limitations or hidden costs.

What is the difference between blur and spread?+

Blur radius controls how soft or sharp the shadow edges are - higher blur values create softer, more diffused shadows, while lower values create sharper, more defined edges. Spread radius controls how much the shadow expands or contracts from the element - positive values make the shadow larger, while negative values make it smaller than the element itself.

Can I create multiple shadows on one element?+

Yes, you can add multiple box-shadow effects by separating them with commas in the CSS. This creates layered shadow effects, allowing you to combine different shadow styles for more complex and visually appealing designs. Our generator supports this feature, and you can manually combine multiple shadow values in your CSS.

What are inset shadows?+

Inset shadows appear inside the element instead of outside, creating effects like pressed buttons, inner glows, or recessed panels. When the inset option is enabled, the shadow is rendered within the element's boundaries, giving it a sunken or embossed appearance that's perfect for creating depth and dimension in UI elements.

Will these shadows work in all browsers?+

Yes, the CSS box-shadow property is well-supported in all modern browsers including Chrome, Firefox, Safari, Edge, and Opera. The generated CSS will work across all current web browsers. For older browsers (IE8 and below), you may need fallback solutions, but all modern browsers fully support box-shadow without any issues.

How do I use the generated CSS code?+

Simply copy the generated CSS code from the tool and paste it into your stylesheet or inline style attribute. The code follows the standard CSS box-shadow syntax: box-shadow: [offset-x] [offset-y] [blur] [spread] [color]. You can apply it to any HTML element by adding it to the element's style property or CSS class.

Can I save my shadow configurations?+

While the tool doesn't have a built-in save feature, you can easily copy the generated CSS code and save it in your own code repository, notes, or design system documentation. The CSS values are standard and can be reused anytime by pasting them back into your stylesheet.
