transition-timing-function x483p
The transition-timing-function property is used to specify a timing function which defines the speed over time of an object being transitioned from one value to another. 203551
It describes how a transition will progress over one cycle of its duration, allowing a it to change speed during its course.
A timing function in CSS describes how intermediate values during a transition will be calculated, and are usually referred to in CSS as easing functions.
The transition-timing-function takes a timing function as a value, which is a mathematical function that specifies the speed over time of an object being transitioned from one value to another. It can also be defined using one of several predefined keywords for common timing functions.
If you define more than one transition-property property.
It is usually more convenient to specify the transition-timing-function in the transition shorthand property.

- Syntax:
transition-timing-function: <timing-function>
- Initial: ease
- Applies To: all elements; and

See the
<timing-function>entry for a list of possible values, detailed explanation of each, and examples and demos for each value.
Examples 3e5p5z
The following specifies a hover from one background color to another using a predefined timing function keyword.
.element {
background-color: #009966;
transition-property: background-color;
transition-duration: .3s;
transition-timing-function: ease-out;
}
.element:hover {
background-color: #0098D8;
}
The following are all valid transition-timing-function values:
transition-timing-function: linear;
transition-timing-function: cubic-bezier(0.42, 0, 1, 1); /* equivalent to the "ease-in" keyword */
transition-timing-function: steps(4, start); /* make transition over 4 steps */
transition-timing-function: ease-in-out;
See the <timing-function> entry for more values and examples.
Live Demo 2x4j2k
In the following demo, an element is transitioned from one position to another by transitioning its offset value, and its background color is also transitioned. Try changing the transition-timing-function value to see how the effect or “feel” of the transition changes.
