Quick Reference
The animation-timing-function defines the speed curve of an animation, which is the time it takes to change from one set of styles to another (how smoothly it changes).
div {
animation-timing-function: linear;
}
Values
| Default value | ease |
| Inherited values | no |
| Can it be animated? | no |
These are the allowed values.
| Value | Description |
|---|---|
| linear | The animation has the same speed from start to end |
| ease | The animation has a slow start, then fast, before it ends slowly (default) |
| ease-in | The animation has a slow start |
| ease-out | The animation has a slow end |
| ease-in-out | The animation has both a slow start and a slow end |
| 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 and must be a positive integer greater than 0; the second parameter, which is optional, is either the value “start” or “end” (default), and specifies the point at which the change of values occur within the interval |
| cubic-bezier(n,n,n,n) | Define your own values in the cubic-bezier function; possible values are numeric from 0 to 1 |
| initial | Sets this property to its default value |
| inherit | Inherits this property from its parent element |
Using JavaScript
The HTML element can also be styled using JavaScript and the element’s id.
document.getElementById('my_div').style.animationTimingFunction = 'linear';
<button onclick='my_function()'>Click Here</button>
<script>
function my_function() {
document.getElementById('my_div').style.animationTimingFunction = 'linear';
}
</script>
We’d like to acknowledge that we learned a great deal of our coding from W3Schools and TutorialsPoint, borrowing heavily from their teaching process and excellent code examples. We highly recommend both sites to deepen your experience, and further your coding journey. We’re just hitting the basics here at 1SMARTchicken.
