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.
