The `opacity` property sets the opacity level for an element. The opacity level describes the transparency level, where `1` is not transparent at all, `.5` is 50% visible, and `0` is completely transparent.
Set the `opacity` of an element using `.opacity-{value}` utilities.
<div class="bd-example d-sm-flex">
<div class="opacity-100 p-3 m-2 bg-primary text-light fw-bold rounded">100%</div>
<div class="opacity-75 p-3 m-2 bg-primary text-light fw-bold rounded">75%</div>
<div class="opacity-50 p-3 m-2 bg-primary text-light fw-bold rounded">50%</div>
<div class="opacity-25 p-3 m-2 bg-primary text-light fw-bold rounded">25%</div>
</div>
```html
<div class="opacity-100">...</div>
<div class="opacity-75">...</div>
<div class="opacity-50">...</div>
<div class="opacity-25">...</div>
