Examples
Basic example
Use utilities like backdrop-opacity-50 and backdrop-opacity-75 to control the opacity of all the backdrop filters applied to an element:
backdrop-opacity-10
backdrop-opacity-60
backdrop-opacity-95
<div class="bg-[url(/img/mountains.jpg)]"> <div class="bg-white/30 backdrop-invert backdrop-opacity-10 ..."></div></div><div class="bg-[url(/img/mountains.jpg)]"> <div class="bg-white/30 backdrop-invert backdrop-opacity-60 ..."></div></div><div class="bg-[url(/img/mountains.jpg)]"> <div class="bg-white/30 backdrop-invert backdrop-opacity-95 ..."></div></div>Using a custom value
Use the backdrop-opacity-[<value>] syntax to set the backdrop filter opacity based on a completely custom value:
<div class="backdrop-opacity-[.15] ..."> <!-- ... --></div>For CSS variables, you can also use the backdrop-opacity-(<custom-property>) syntax:
<div class="backdrop-opacity-(--my-backdrop-filter-opacity) ..."> <!-- ... --></div>This is just a shorthand for backdrop-opacity-[var(<custom-property>)] that adds the var() function for you automatically.
Responsive design
Prefix a backdrop-filter: opacity() utility with a breakpoint variant like md: to only apply the utility at medium screen sizes and above:
<div class="backdrop-opacity-100 md:backdrop-opacity-60 ..."> <!-- ... --></div>Learn more about using variants in the variants documentation.
