CSS Transition Generator
CSS Transition Generator
Create smooth CSS transitions with custom timing functions - free generator with live preview
transition: all 0.3s ease;What is CSS Transition Generator?
CSS transitions enable smooth animations between property values when they change. This free CSS Transition Generator helps web developers create professional animations for hover effects, state changes, and interactive elements. Instead of instant property changes, transitions animate smoothly over a specified duration. You can control which property animates, how long it takes, the acceleration curve (timing function), and an optional delay. Our generator provides real-time preview so you can see exactly how your transition will feel. Transitions are essential for creating polished user interfaces that feel responsive and professional.
How to Use This Tool

Set the duration - how long the transition takes (300ms is a good default)
Choose a timing function to control the animation curve
Add a delay if you want the transition to wait before starting
Hover over the preview to see the transition in action
Copy the generated CSS code and apply it to your elements

Frequently Asked Questions
- What is a CSS transition?
A CSS transition animates property changes smoothly over time instead of instantly. Syntax: transition: property duration timing-function delay;. For example: transition: opacity 0.3s ease; animates opacity changes over 300ms.
- What is the best duration for CSS transitions?
For most UI interactions, 200-400ms feels natural. Faster (100-200ms) for small elements like buttons. Slower (400-600ms) for larger elements or dramatic effects. Avoid transitions over 1 second as they feel sluggish.
- What are CSS timing functions?
Timing functions control the acceleration curve. ease (default) starts slow, speeds up, ends slow. linear is constant speed. ease-in starts slow. ease-out ends slow. ease-in-out combines both. You can also use cubic-bezier() for custom curves.
- Should I use transition: all or specific properties?
For performance, specify properties: transition: transform 0.3s, opacity 0.3s;. Using "all" is convenient but may animate properties unintentionally and can be less performant. Always specify properties in production code.
- What is the difference between CSS transition and animation?
Transitions animate between two states (like hover). Animations use @keyframes for complex multi-step sequences that can loop and run automatically. Use transitions for simple state changes, animations for complex effects.
- Why is my CSS transition not working?
Common issues: the property cannot be animated (like display), no state change triggers it, the property is set with !important, or the element has display: none. Also ensure the transition is on the base state, not the hover state.
