CSS Transition Generator

Generate CSS transitions with customizable property, duration, easing, and hover effects.

How to Use

Set transition properties

Choose the CSS property to transition, duration, timing function, and delay.

Define hover state

Test and copy

Hover over the preview element to test the transition, then copy the CSS.

What Is CSS Transition Generator?

The CSS Transition Generator creates smooth state transitions between CSS property values. Unlike animations that can run automatically, transitions require a trigger—typically a hover, focus, or active state. This tool lets you configure every transition parameter: which property to target, how long the transition takes, which easing function to use, and how long to delay before starting. It includes standard easing functions plus popular cubic-bezier presets like ease-in-back, ease-out-back, and ease-in-out-back for bouncy effects. The hover state section lets you define what changes on hover—background color, scale, border radius, and rotation—so you can see and test the transition in real-time by hovering over the preview element.

Technical Guide

The CSS transition property is shorthand for transition-property, transition-duration, transition-timing-function, and transition-delay. The transition-property can target specific properties or use all for everything. Duration and delay use seconds or milliseconds. The timing function defines the speed curve: linear is constant speed, ease starts slow then speeds up then slows down, ease-in starts slow, ease-out ends slow. Custom curves use the cubic-bezier(x1, y1, x2, y2) function where the four values define control points. Values outside 0-1 for y create overshoot/bounce effects. For performance, transition only transform and opacity when possible. Multiple transitions can be defined with comma-separated values for different properties with different timings. Transitions are triggered by any property change, including JavaScript-set values and class additions.

Tips & Best Practices

1
Target specific properties instead of all for better performance
2
Use cubic-bezier values >1 for y-coordinates to create bounce effects
3
Keep transitions under 300ms for UI interactions for snappy feel
4
Add transition to the base state, not the hover state

Frequently Asked Questions

QWhat is the difference between transition and animation?

Transitions need a trigger and animate between two states. Animations can run automatically with multiple stages.

QCan I transition multiple properties?

Yes, use comma-separated values or transition: all to affect all properties.

QWhich easing function should I use?

ease-out is best for entrances, ease-in for exits, ease-in-out for state changes, and linear for continuous motion.

QWhy is my transition not working?

Ensure the property is animatable, the transition is on the base state (not hover), and you are changing a specific CSS value.

QCan all CSS properties be transitioned?

No, only properties with intermediate values can transition. Properties like display switch instantly.
