# Z-index

The following classes control the z-index of elements:

## `.z-index-{value}`, `.z-{value}`

Sets the z-index property to the specified positive value, adjusting the stacking order of the element.

CSS equivalent: `z-index: {value};`

Example usage:

```html
<div class="z-index-1">
  <!-- Content with z-index 1 -->
</div>
```

or

```html
<div class="z-1">
  <!-- Content with z-index 1 -->
</div>
```

***

## `.z-index--{value}`, `.z--{value}`

Sets the z-index property to the specified negative value, adjusting the stacking order of the element.

CSS equivalent: `z-index: -{value};`

Example usage:

```html
<div class="z-index--1">
  <!-- Content with z-index -1 -->
</div>
```

or

```html
<div class="z--1">
  <!-- Content with z-index -1 -->
</div>
```

***

These utility classes allow you to easily control the stacking order of elements by specifying their z-index values. Positive values bring elements forward in the stacking order, while negative values send elements backward.
