CSS Gradient Generator

What is a CSS Gradient?

CSS gradients render smooth color transitions directly in the browser — no image files, no extra HTTP requests, no size penalty for high-DPI displays. They were standardized in CSS Image Values Module Level 3 (W3C, 2014) and are supported in all browsers since IE10. Modern gradients support unlimited color stops, transparency, hard color stops (sharp lines), and gradient color spaces (CSS Color Module Level 4).

Three gradient types

• linear-gradient() — straight-line transitions (vertical, horizontal, diagonal)
• radial-gradient() — radiating from a center point (circle or ellipse)
• conic-gradient() — rotating around a center point (used for pie charts, color wheels)

All three have repeating-* variants (repeating-linear-gradient, etc.) for repeating patterns like stripes, plaid, or checkerboards.

Why gradients beat images

For solid color transitions, CSS gradients are infinitely smaller, infinitely scalable, and instantly customizable. A 1MB hero image with a color gradient becomes 50 bytes of CSS. They render at any resolution without aliasing, animate smoothly, and respect accessibility preferences (reduced motion). For UI design in 2026, gradients are the default; PNG backgrounds are the exception.
