With ease-in, colors cluster near the end — the transition starts slowly then accelerates. With ease-out, colors cluster near the beginning — fast start, gentle finish. Ease-in-out clusters colors in the middle, creating a smooth S-curve. This gives designers fine control over the "rhythm" of a gradient, making backgrounds feel more organic.

Yes — CSS transition-timing-function controls animation speed over time. Easing gradients control spatial color distribution within a static gradient image. However, they use the same cubic-bezier math under the hood. This tool applies those familiar easing curves to gradient color-stop positions.

ease-in-out is the most versatile — balanced and natural. ease-out works well for light sources (bright center fading outward). ease-in creates dramatic depth (dark edges pulling inward). Try ease-out-elastic or ease-out-bounce for playful, attention-grabbing effects.

A cubic-bezier curve is defined by four values: cubic-bezier(x1, y1, x2, y2). x1 and x2 must be between 0 and 1, representing time progression. y1 and y2 define the easing "overshoot" — values outside [0,1] create elastic or bounce-like effects. The curve maps input progress (0→1) to output value via two control points.

Yes! The generated CSS uses standard linear-gradient(), radial-gradient(), or conic-gradient() with percentage-based color stops. All modern browsers (Chrome, Firefox, Safari, Edge) fully support these. No JavaScript is needed for the gradient to render — the easing is "baked" into the stop positions.

Absolutely. While the gradient itself is static CSS, easing gradients pair beautifully with @keyframes animations. Shift the gradient position with background-position or animate the angle to create flowing, organic motion that feels more natural thanks to the non-linear color distribution.

2–3 stops create clean, modern gradients. 4–6 stops allow for complex, rich transitions (sunsets, auroras, metallic effects). More than 6 stops can become visually busy — but the tool supports up to 8 for advanced use cases. The easing function distributes all stops non-uniformly for maximum impact.
