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

Browser Support
The transition-timing-function property is supported in Internet Explorer 10, Firefox, Opera, and Chrome.
Safari supports an alternative, the -webkit-transition-timing-function property.
Note: The transition-timing-function property is not supported in Internet Explorer 9 and earlier versions.
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 |
| Version: | CSS3 |
| JavaScript syntax: | object.style.transitionTimingFunction="linear" |
Syntax
transition-timing-function: linear|ease|ease-in|ease-out|ease-in-out|cubic-bezier(n,n,n,n);
| Value | Description |
|---|---|
| linear | Specifies a transition effect with the same speed from start to end (equivalent to cubic-bezier(0,0,1,1)) |
| ease | Specifies a transition effect with a slow start, then fast, then end slowly (equivalent to cubic-bezier(0.25,0.1,0.25,1)) |
| 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)) |
| cubic-bezier(n,n,n,n) | Define your own values in the cubic-bezier function. Possible values are numeric values from 0 to 1 |

Example
To better understand the different function values: Here are five different div elements with five different values:
#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;}
/* Safari */
#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;}
#div2 {transition-timing-function: ease;}
#div3 {transition-timing-function: ease-in;}
#div4 {transition-timing-function: ease-out;}
#div5 {transition-timing-function: ease-in-out;}
/* Safari */
#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;}

Example
Same as the example above, but the speed curves are specified with the cubic-bezier function:
#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);}
/* Safari */
#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);}
#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);}
/* Safari */
#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);}
