The CSS Transition Generator lets you build the CSS transition property visually. Choose which property to animate, set the duration, easing curve, and delay, and preview the motion live by hovering or clicking Play — then copy ready-to-use CSS without memorising the shorthand order.
You can layer several transitions on one element — for example animating transform and opacity together with different timings — and copy the result as plain CSS or a Tailwind arbitrary-value class. Everything runs in your browser.
How to use the CSS transition generator
- Pick the property to animate (or “all”), then set the duration in milliseconds.
- Choose a timing function such as ease, ease-in-out, or a bouncy cubic-bezier, and add a delay if needed.
- Click Play (or hover the preview) to watch the transition, and add more rows to animate several properties.
- Copy the generated CSS (or Tailwind class) and paste it into your stylesheet.
The transition shorthand
The transition shorthand combines four values in order: the property to animate, the duration, the timing function, and the delay — for example transition: transform 300ms ease-in-out 100ms. Only the property and duration are required; this tool omits a delay of 0 to keep the output clean, and writes each value in the correct order for you.
Choosing a timing function
The timing function controls how speed is distributed across the transition. ease starts and ends gently, linear moves at a constant rate, and ease-in / ease-out accelerate or decelerate. For more character you can use a cubic-bezier curve — the “Bounce” preset overshoots and settles, while “Smooth” is the Material-style standard curve. If you need a custom curve, design it with the cubic-bezier generator and paste it in.
Transitioning multiple properties
You can animate several properties at once by separating transitions with commas, and this tool builds that list for you. Animating specific properties (like transform and opacity) is usually better for performance than transition: all, because the browser only watches the properties you name. transform and opacity in particular are GPU-accelerated and the smoothest to animate.
Frequently Asked Questions
What does the CSS transition property do?
It smoothly animates a property from its old value to a new one over time when that value changes — for example on hover, focus, or when a class is toggled — instead of snapping instantly.
What is the order of values in the transition shorthand?
Property, duration, timing function, then delay — e.g. transition: opacity 200ms ease-in 50ms. Duration comes before delay when both are present, which this tool handles automatically.
Can I transition more than one property?
Yes. Click “Add transition” to animate another property with its own duration and easing. Multiple transitions are separated by commas, which this generator does for you.
Which properties are cheapest to animate?
transform and opacity are GPU-accelerated and animate most smoothly. Animating layout properties like width, height, or margin is more expensive because it forces the browser to recalculate layout.
Can I get the transition as a Tailwind class?
Yes. Switch the output to “Tailwind” to get an arbitrary [transition:…] class. Underscores stand in for spaces in Tailwind arbitrary values.
Do CSS transitions work in all browsers?
Yes. The transition property is supported in all modern browsers, so the generated CSS works everywhere without vendor prefixes.
