## Examples

### Width base and percentage units

```html
<div class="ws-example-u-sizing-item pf-v6-u-w-0">.pf-v6-u-w-0</div>
<div class="ws-example-u-sizing-item pf-v6-u-w-25">.pf-v6-u-w-25</div>
<div class="ws-example-u-sizing-item pf-v6-u-w-50">.pf-v6-u-w-50</div>
<div class="ws-example-u-sizing-item pf-v6-u-w-75">.pf-v6-u-w-75</div>
<div class="ws-example-u-sizing-item pf-v6-u-w-100">.pf-v6-u-w-100</div>
<div
  class="ws-example-u-sizing-item pf-v6-u-w-initial"
>.pf-v6-u-w-initial (auto)</div>
<div class="ws-example-u-sizing-item pf-v6-u-w-inherit">.pf-v6-u-w-inherit</div>

```

### Usage

[Breakpoints](/foundations-and-styles/design-tokens/all-design-tokens) are optional. Breakpoint options include: base (no breakpoint value), `-on-sm`, `-on-md`, `-on-lg`, and `-on-xl`. Example: `.pf-v6-u-w-initial-on-lg`

| Class | Applied to | Outcome |
| -- | -- | -- |
| `.pf-v6-u-w-initial{-on-[breakpoint]}` | `*` | Sets width: initial (auto) |
| `.pf-v6-u-w-inherit{-on-[breakpoint]}` | `*` | Sets width: inherit |
| `.pf-v6-u-w-0{-on-[breakpoint]}`  | `*` | Sets width: 0% |
| `.pf-v6-u-w-25{-on-[breakpoint]}` | `*` | Sets width: 25% |
| `.pf-v6-u-w-33{-on-[breakpoint]}` | `*` | Sets width: calc(100% / 3) |
| `.pf-v6-u-w-50{-on-[breakpoint]}` | `*` | Sets width: 50% |
| `.pf-v6-u-w-66{-on-[breakpoint]}` | `*` | Sets width: calc(100% / 3 \* 2) |
