What this tool does
This generator builds a ready-to-paste CSS transition shorthand from four parts: the property to animate, how long the animation lasts in seconds, the timing function that shapes its speed curve, and an optional delay before it starts. As you change any field, the code updates instantly and a live preview box animates whenever you hover it, so you can feel exactly how your settings behave before copying them into your stylesheet. The output follows the standard property duration timing delay order, and a zero delay is left out to keep the value clean and minimal.
Choosing duration, timing, and delay
Duration and delay are entered in seconds and can use decimals such as 0.3 or 0.15 for snappy micro-interactions. The timing function controls acceleration: ease starts and ends gently, linear keeps a constant speed, ease-in and ease-out ramp at one end, and cubic-bezier() lets you craft a custom curve. Setting the property to all animates every animatable property at once, while naming a single property like opacity or transform keeps the effect focused and performant. The same inputs always produce the same output, so the generated value is predictable and safe to reuse.
Frequently asked questions
Why is the delay missing from my transition value?
A delay of 0 seconds is intentionally omitted because it has no effect. The tool outputs just "property duration timing" in that case, which is the cleanest valid form. Enter any non-zero delay and it is appended at the end, for example "opacity 0.5s ease-in-out 0.2s".
How do I animate only one property instead of all?
Pick a specific property such as opacity, transform, or background-color from the property field instead of "all". Animating a single, cheap-to-render property like transform or opacity is usually smoother than animating "all".
Is anything I type uploaded to a server?
No. Every value is computed locally in your browser with JavaScript. Nothing you enter is sent, logged, or stored anywhere — the tool works fully offline once the page has loaded.
