A CSS transition generator lets you visually configure smooth property changes without writing CSS manually. Set the property, duration, timing function, and delay — then preview and copy the transition shorthand to use in your hover effects and state changes.

How to Use the CSS Transition Generator
CSS transitions are one of the most powerful tools for creating polished UIs. A simple hover effect on a button can make a site feel modern or flat depending on the transition settings. This free CSS transition generator makes it easy to find the right combination before writing any code.
Step 1: Choose a Property
Select which CSS property to transition. Use all to transition every animatable property, or choose a specific property like transform (for scale/rotate/translate), opacity (for fades), or background-color (for color changes). Different properties have different visual effects.
Step 2: Set Duration and Timing Function
Duration controls how long the transition takes. Most UI transitions work best between 150ms and 400ms — shorter feels snappy, longer feels smooth. The timing function controls acceleration: ease is the most natural for most UI elements. ease-out feels responsive because it starts fast. The spring option creates an overshoot bounce effect.
Step 3: Add a Delay (Optional)
Delay adds a pause before the transition starts. This is useful for staggering multiple elements or adding a hover pause before a navigation menu opens. Keep delay under 0.2s for interactive elements — longer delays feel laggy.
Step 4: Test with the Preview
Click the preview box or the Trigger button to toggle the transition and see how it feels at your current settings. The box transforms between its default state and an active state so you can feel the timing and easing in real time.
Step 5: Copy and Apply
Click Copy CSS to copy the complete transition shorthand. Add it to your element's default state CSS. The transition will automatically apply whenever any of the specified properties change.
FAQ
Is this CSS transition generator free?
Yes, completely free with no limits or account required. All preview rendering and CSS generation happen locally in your browser.
What is a CSS transition?
A CSS transition animates property changes smoothly over a specified duration. When a property value changes (e.g., on hover), instead of jumping instantly to the new value, the browser interpolates between the old and new values over the transition duration.
What is the difference between transitions and animations?
Transitions require a trigger (like hover or class change) to animate between two states. Animations with @keyframes can run automatically, loop, and define multiple intermediate states. Use transitions for simple hover effects; use animations for continuous or multi-step motion.
How does the cubic-bezier timing function work?
cubic-bezier(x1, y1, x2, y2) defines a custom acceleration curve using two control points. Values between 0-1 for X and 0-1 for Y stay within standard bounds. Values outside 0-1 on Y create overshoot (spring) effects. Sites like cubic-bezier.com help visualize custom curves.
Can I transition multiple properties at once?
Yes. Use 'all' to transition all animatable properties, or list them comma-separated: transition: opacity 0.3s ease, transform 0.5s ease-out. Each property can have its own duration and timing function.
What CSS properties can be transitioned?
Most CSS properties with numeric or color values can be transitioned: opacity, transform, background-color, width, height, padding, margin, border-radius, box-shadow, color, and many more. Properties like display and visibility cannot be transitioned.
What is transition-delay?
transition-delay specifies how long to wait before starting the transition after the trigger occurs. A 0.2s delay means the browser waits 200ms after the hover/class change before beginning the animation. Useful for staggering multiple elements.
