title: Easing variables

Variables that can be reused for `transition-timing-function` properties, more powerful than the built-in `ease`, `ease-in`, `ease-out` and `ease-in-out`.
|
|
|
|
- The variables are defined globally within the `:root` CSS pseudo-class which matches the root element of a tree representing the document.
|
|
- In HTML, `:root` represents the `<html>` element and is identical to the selector `html`, except that its specificity is higher.
|
|
|
|
```html
|
|
<div class="easing-variables">Hover</div>
|
|
```
|
|
|
|
```css
|
|
:root {
|
|
/* Place variables in here to use globally */
|
|
}
|
|
|
|
