ease-in or cubic-bezier redistributes them — creating more dynamic, natural-looking transitions that mimic real-world lighting and motion.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.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.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.@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.Design borders with linear or conic gradients.
