### Sibling fade

Fades out the siblings of a hovered item.

#### HTML

```html
<div class="sibling-fade">
  <span>Item 1</span>
  <span>Item 2</span>
  <span>Item 3</span>
  <span>Item 4</span>
  <span>Item 5</span>
  <span>Item 6</span>
</div>
```

#### CSS

```css
span {
  padding: 0 1rem;
  transition: opacity 0.2s;
}

.sibling-fade:hover span:not(:hover) {
  opacity: 0.5;
}
```

#### Demo

#### Explanation

1. `transition: opacity 0.2s` specifies that changes to opacity will be transitioned over 0.2 seconds.
2. `.sibling-fade:hover span:not(:hover)` specifies that when the parent is hovered, select any `span` children
   that are not currently being hovered and change their opacity to `0.5`.
