Frequently Asked Questions

What is a CSS Gradient?

A CSS gradient is a smooth transition between two or more colors, rendered directly by the browser without needing an image file. CSS defines three types: linear gradients (along a straight line), radial gradients (from a center point outward), and conic gradients (rotating around a center point). Use our Gradient Generator to build any of these visually.

What is a CSS Box Shadow?

The CSS box-shadow property adds shadow effects around an element's frame. You can set multiple layers, each with its own horizontal offset, vertical offset, blur radius, spread radius, color and opacity. Box shadows are essential for creating depth, elevation and modern card-style UI designs.

What is Glassmorphism?

Glassmorphism is a UI design trend that uses a frosted glass effect — achieved in CSS using backdrop-filter: blur() combined with a semi-transparent background. The result is a modern, translucent look popularised by Apple's macOS design language.

Do CSSTools.io generators work on mobile?

Yes — all CSSTools.io generators are responsive and run in any modern browser, including mobile Chrome, Safari and Firefox. The interactive sliders and preview panels are touch-friendly on phones and tablets.
