Opacity

Control the opacity of elements.

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.

100%
75%
50%

<div class="opacity-100">...</div>
<div class="opacity-75">...</div>
<div class="opacity-50">...</div>
<div class="opacity-25">...</div>
<div class="opacity-0">...</div>
