## Relative to the parent

Width and height utilities are generated from the utility API in `_utilities.scss`. Includes support for `25%`, `50%`, `75%`, `100%`, and `auto` by default. Modify those values as you need to generate different utilities here.

<Example
  class="bd-example-flex"
  html={`<div class="w-25 p-3">Width 25%</div>
<div class="w-50 p-3">Width 50%</div>
<div class="w-75 p-3">Width 75%</div>
<div class="w-100 p-3">Width 100%</div>
<div class="w-auto p-3">Width auto</div>`}
/>

<Example
  class="bd-example-flex"
  html={`<div style="height: 100px;">
    <div class="h-25 d-inline-block" style="width: 120px;">Height 25%</div>
    <div class="h-50 d-inline-block" style="width: 120px;">Height 50%</div>
    <div class="h-75 d-inline-block" style="width: 120px;">Height 75%</div>
    <div class="h-100 d-inline-block" style="width: 120px;">Height 100%</div>
    <div class="h-auto d-inline-block" style="width: 120px;">Height auto</div>
  </div>`}
/>

You can also use `max-width: 100%;` and `max-height: 100%;` utilities as needed.

<Example
  class="bd-example-flex"
  html={`<div style="width: 50%; height: 100px;">
    <div class="mw-100" style="width: 200%;">Max-width 100%</div>
  </div>`}
/>

<Example
  class="bd-example-flex"
  html={`<div style="height: 100px;">
    <div class="mh-100" style="width: 100px; height: 200px;">Max-height 100%</div>
  </div>`}
/>

## Relative to the viewport

You can also use utilities to set the width and height relative to the viewport.

```html
<div class="min-vw-100">Min-width 100vw</div>
<div class="min-vh-100">Min-height 100vh</div>
<div class="vw-100">Width 100vw</div>
<div class="vh-100">Height 100vh</div>
```
