About the CSS Transition Generator

The CSS Transition Generator lets you build transition properties visually — no manual CSS editing required. Add multiple transition layers for different CSS properties, adjust duration, choose a timing function, set a delay, and watch the live preview react instantly.

CSS transitions are one of the most powerful tools for creating smooth, polished UI interactions. This generator supports all standard transition-property values, the five CSS timing functions plus cubic-bezier() and steps(), and up to six simultaneous layers so you can fine-tune how each property animates independently.

How to Generate a CSS Transition

  1. Click a Preset to load a ready-made transition set, or start from the defaults.
  2. Click + Add to add a new layer for an additional CSS property.
  3. Click any layer in the list to make it active and edit its settings.
  4. Select the Property you want to animate (e.g. opacity, transform).
  5. Drag the Duration slider to control how long the transition takes.
  6. Choose a Timing Function — ease-out feels natural for most UI interactions.
  7. Set a Delay to stagger transitions for a cascading effect.
  8. Hover over the preview box to see the transitions in action.
  9. Click Copy CSS to grab the generated transition rule.

Common Use Cases for CSS Transitions

  • Button hover effects — Smoothly animate background-color, box-shadow, and transform on hover for polished button interactions.
  • Fade in/out — Transition opacity to softly reveal or hide content like tooltips, modals, and dropdowns.
  • Slide and reveal — Combine max-height or transform transitions to create accordion and drawer expand animations.
  • Color scheme changes — Smoothly switch background-color and color when toggling dark mode or theming.
  • Staggered cascades — Use transition-delay on list items to animate them in sequence for a flowing entrance effect.
  • Form focus states — Transition border-color, box-shadow, and background-color on inputs to give clear, satisfying focus feedback.

CSS Transition FAQ

What is the difference between a CSS transition and a CSS animation?

A transition interpolates between two states (from and to) triggered by a state change like :hover. An @keyframes animation runs independently and can loop, reverse, and define multiple intermediate states without any trigger.

Can I transition multiple properties at once?

Yes. The transition property accepts a comma-separated list, allowing each property to have its own duration, timing function, and delay. Using transition: all is a shortcut but can be less performant — prefer listing specific properties.

Which properties can be transitioned?

Most properties with numeric or color values can be transitioned: opacity, transform, color, background-color, width, height, border-radius, box-shadow, and more. Discrete properties like display cannot be transitioned.

What is a transition timing function?

The timing function controls the rate of change over the transition duration. ease is the default with a slow start and end. linear keeps constant speed. ease-out starts fast and decelerates — great for enter animations. cubic-bezier() lets you define a fully custom curve.

Should I use `transition: all` or list specific properties?

Listing specific properties is recommended for performance. transition: all watches every property for changes, which can cause unexpected animations and reduce rendering performance on complex elements.

Are CSS transitions hardware-accelerated?

Transitions on transform and opacity are composited on the GPU in modern browsers, making them the smoothest and most performant properties to animate. Avoid transitioning layout-affecting properties like width or margin in performance-critical UIs.
