## Box Shadow

Use the `shadow` or `boxShadow` prop to apply a box shadow to an element.

```jsx
// hardcoded values
<Box shadow="12px 12px 2px 1px rgba(0, 0, 255, .2)" />

// token values
<Box shadow="lg" />
```

| Prop                   | CSS Property     | Token Category |
| ---------------------- | ---------------- | -------------- |
| `shadows`, `boxShadow` | `box-shadow`     | `shadows`      |
| `shadowColor`          | `--shadow-color` | `colors`       |

## Box Shadow Color

Use the `shadowColor` prop to set the color of a box shadow. This prop maps to
the `--shadow-color` CSS variable.

```jsx
<Box shadow="60px -16px var(--shadow-color)" shadowColor="red" />
```

| Prop          | CSS Property     | Token Category |
| ------------- | ---------------- | -------------- |
| `shadowColor` | `--shadow-color` | `colors`       |

## Opacity

Use the `opacity` prop to set the opacity of an element.

```jsx
<Box opacity="0.5" />
```

| Prop      | CSS Property | Token Category |
| --------- | ------------ | -------------- |
| `opacity` | `opacity`    | `opacity`      |

## Mix Blend Mode

Use the `mixBlendMode` prop to control how an element's content should be
blended with the background.

```jsx
<Box bg="red.400">
  <Image src="..." mixBlendMode="hard-light" />
</Box>
```

| Prop           | CSS Property     | Token Category |
| -------------- | ---------------- | -------------- |
| `mixBlendMode` | `mix-blend-mode` | -              |
