These sections explain the job in plain language and set expectations for what the tool should do well.
The CSS cubic-bezier generator helps you craft custom animation easing curves. Adjust the four control points (x1, y1, x2, y2) with sliders or start from a common preset like ease, ease-in, ease-out, ease-in-out, or linear. A live animated dot and the plotted curve show exactly how your timing function feels, and the output gives you both a ready cubic-bezier(...) value and a full transition snippet. It all runs locally in your browser.
Short answers for the questions people usually have before trying a utility like this.
cubic-bezier defines a custom easing curve for CSS transitions and animations, controlling how a property accelerates and decelerates between its start and end values.
They are the x and y coordinates of two control points (x1, y1, x2, y2). The x values must stay between 0 and 1, while y values can go beyond that range to create bounce or overshoot effects.
That happens when a y control point is above 1 or below 0, which pushes the animation past its endpoints. It is a valid, intentional easing effect and the exact behavior your copied cubic-bezier value will produce.
