CSS3 transition-timing-function Property
Example
A transition effect with the same speed from start to end:
div {
-webkit-transition-timing-function: linear; /* Safari and Chrome */
transition-timing-function: linear;
}

Definition and Usage
The transition-timing-function property specifies the speed curve of the transition effect.
This property allows a transition effect to change speed over its duration.
| Default value: | ease |
|---|---|
| Inherited: | no |
| Animatable: | no. Read about animatable |
| Version: | CSS3 |
| JavaScript syntax: | object.style.transitionTimingFunction="linear" Try it |
Browser Support
The numbers in the table specify the first browser version that fully supports the property.
Numbers followed by -webkit-, -moz- or -o- specify the first version that worked with a prefix.

CSS Syntax
transition-timing-function: linear|ease|ease-in|ease-out|ease-in-out|step-start|step-end|steps(int,start|end)|cubic-bezier(n,n,n,n)|initial|inherit;
Property Values
| Value | Description |
|---|---|
| ease | Default value. Specifies a transition effect with a slow start, then fast, then end slowly (equivalent to cubic-bezier(0.25,0.1,0.25,1)) |
| linear | Specifies a transition effect with the same speed from start to end (equivalent to cubic-bezier(0,0,1,1)) |
| ease-in | Specifies a transition effect with a slow start (equivalent to cubic-bezier(0.42,0,1,1)) |
| ease-out | Specifies a transition effect with a slow end (equivalent to cubic-bezier(0,0,0.58,1)) |
| ease-in-out | Specifies a transition effect with a slow start and end (equivalent to cubic-bezier(0.42,0,0.58,1)) |
| step-start | Equivalent to steps(1, start) |
| step-end | Equivalent to steps(1, end) |
| steps(int,start|end) | Specifies a stepping function, with two parameters. The first parameter specifies the number of intervals in the function. It must be a positive integer (greater than 0). The second parameter, which is optional, is either the value "start" or "end", and specifies the point at which the change of values occur within the interval. If the second parameter is omitted, it is given the value "end" |
| cubic-bezier(n,n,n,n) | Define your own values in the cubic-bezier function. Possible values are numeric values from 0 to 1 |
| initial | Sets this property to its default value. Read about initial |
| inherit | Inherits this property from its parent element. Read about inherit |
Tip: Try the different values in the examples below to understand how it works!
More Examples
Example
To better understand the different function values: Here are five different div elements with five different values:
/* For Safari 3.1 to 6.0 */
#div1 {-webkit-transition-timing-function: linear;}
#div2 {-webkit-transition-timing-function: ease;}
#div3 {-webkit-transition-timing-function: ease-in;}
#div4 {-webkit-transition-timing-function: ease-out;}
#div5 {-webkit-transition-timing-function: ease-in-out;}
/* Standard
syntax */
#div1 {transition-timing-function: linear;}
#div2 {transition-timing-function: ease;}
#div3 {transition-timing-function: ease-in;}
#div4 {transition-timing-function: ease-out;}
#div5 {transition-timing-function: ease-in-out;}

Example
Same as the example above, but the speed curves are specified with the cubic-bezier function:
/* For Safari 3.1 to 6.0 */
#div1 {-webkit-transition-timing-function: cubic-bezier(0,0,1,1;}
#div2 {-webkit-transition-timing-function: cubic-bezier(0.25,0.1,0.25,1);}
#div3 {-webkit-transition-timing-function: cubic-bezier(0.42,0,1,1);}
#div4 {-webkit-transition-timing-function: cubic-bezier(0,0,0.58,1);}
#div5 {-webkit-transition-timing-function: cubic-bezier(0.42,0,0.58,1);}
/* Standard syntax */
#div1 {transition-timing-function: cubic-bezier(0,0,1,1;}
#div2 {transition-timing-function: cubic-bezier(0.25,0.1,0.25,1);}
#div3 {transition-timing-function: cubic-bezier(0.42,0,1,1);}
#div4 {transition-timing-function: cubic-bezier(0,0,0.58,1);}
#div5 {transition-timing-function: cubic-bezier(0.42,0,0.58,1);}
