What does this tool do?
This CSS transition generator lets you build a ready-to-use transition rule by choosing the property, duration, timing function and delay. A live box that changes on hover shows the effect in real time, and you can copy the result with one click, making it ideal for web developers designing smooth hover and state changes.
How to use it
- Adjust the values and options.
- See the result in the live preview.
- Copy the generated CSS/code into your project.
The four-part transition shorthand
The generated rule combines the transition shorthand from four values: the property (such as all, transform or opacity), duration in seconds, timing function (ease, linear, ease-in-out or a custom cubic-bezier) and delay in seconds. Animating a specific property is usually more performant than using all, because the browser only watches that one property. The preview box shows immediately how the timing you set actually feels in practice.
Choosing the right timing function
The timing function defines the character of a transition. ease gives a natural speed-up then slow-down, while linear keeps a constant pace; ease-in starts slowly and ease-out finishes gently. Values like cubic-bezier(0.68,-0.55,0.27,1.55) in the list create a slight bounce or overshoot. The live preview, where the box grows and rotates on hover, makes it easy to test how each curve feels in motion before you copy the code.
Frequently asked questions
Which properties should I animate with a transition?
For the smoothest results, prefer transform and opacity, since the browser can accelerate them without recalculating layout. Properties like width or height also work but can be more costly.
What does the cubic-bezier option do?
It defines a custom acceleration profile beyond the preset curves. The cubic-bezier value in the list produces a slight bounce or overshoot effect at the end of the transition.
Why would I use a delay value?
Delay makes the transition wait before it starts. It is useful for creating staggered effects by animating several elements one after another with increasing delays.
