What is the CSS Cubic Bezier Generator?

Think of the CSS Cubic Bezier Generator as a remote control for the laws of physics in your web browser. In the world of web design, animations often feel robotic when they move at a constant speed. This tool allows you to act as a "motion architect," defining exactly how an element accelerates and decelerates over time.

By manipulating a mathematical curve, you can create animations that feel organic—like a bouncing ball, a swinging door, or a smooth sliding menu. Whether you are a beginner looking for classic "ease-in-out" presets or a pro crafting high-performance UI transitions, this generator provides the visual precision needed to bring your digital elements to life.

How to Use the Cubic Bezier Generator?

  1. 1
    Shape the Curve:

    Start by selecting a preset easing function or directly drag the control points on the graph to sculpt your custom motion path.

  2. 2
    Fine-Tune Details:
    Coordinates & Duration:Manually input precise X and Y values or adjust the Animation Duration slider to control the timing.
  3. 3
    Test the Motion:

    Watch the live preview box to see your curve in action. Toggle Grid Lines for accuracy or upload a Custom Image to see how your specific UI element will behave.

  4. 4
    Export & Implement:

    Once the motion feels perfect, copy the generated `cubic-bezier()` CSS code and paste it directly into your `transition` or `animation` property.

Pro Tips

"Bouncy" Effects

You can drag control points above 1.0 or below 0.0 to create "anticipation" or "overshoot" (bounce) effects.

Consistency

Use similar bezier curves across your entire site to create a cohesive brand "feeling" in your UI motion.

Duration Matters

A great curve can feel "off" if the duration is too long. Aim for 200ms–500ms for standard UI transitions.
