description: Using CSS animations to animate Chakra UI components
---

We recommend using CSS animations to animate your Chakra UI components. This
approach is performant, straightforward and provides a lot of flexibility.

You can animate both the mounting and unmounting phases of your components with
better control.

## Enter animation

When a disclosure component (popover, dialog) is open, the `data-state`
attribute is set to `open`. This maps to `data-state=open` and can be styled
with `_open` pseudo prop.

```tsx
<Box
  data-state="open"
  _open={{
    animation: "fade-in 300ms ease-out",
  }}
>
  This is open
</Box>
```

Here's an example that uses keyframes to create a fade-in animation:

```css
@keyframes fade-in {
  from {
    opacity: 0;
  }
  to {
    opacity: 1;
  }
}
```

## Exit animation

When a disclosure component (popover, dialog) is closed, the `data-state`
attribute is set to `closed`. This maps to `data-state=closed` and can be styled
with `_closed` pseudo prop.

```tsx
<Box
  data-state="closed"
  _closed={{
    animation: "fadeOut 300ms ease-in",
  }}
>
  This is closed
</Box>
```

Here's an example that uses keyframes to create a fade-out animation:

```css
@keyframes fadeOut {
  from {
    opacity: 1;
  }
  to {
    opacity: 0;
  }
}
```

## Composing animations

Use the `animationName` prop to compose multiple animations together. This makes
it easy to create complex animations with multiple keyframes.

```tsx
<Box
  data-state="open"
  _open={{
    animationName: "fade-in, scale-in",
    animationDuration: "300ms",
  }}
  _closed={{
    animationName: "fade-out, scale-out",
    animationDuration: "120ms",
  }}
>
  This is a composed animation
</Box>
```
