Examples
Basic example
Use utilities like backdrop-brightness-50 and backdrop-brightness-100 to control an element's backdrop brightness:
backdrop-brightness-50
backdrop-brightness-150
<div class="bg-[url(/img/mountains.jpg)]"> <div class="bg-white/30 backdrop-brightness-50 ..."></div></div><div class="bg-[url(/img/mountains.jpg)]"> <div class="bg-white/30 backdrop-brightness-150 ..."></div></div>Using a custom value
Use the backdrop-brightness-[<value>] syntax to set the backdrop brightness based on a completely custom value:
<div class="backdrop-brightness-[1.75] ..."> <!-- ... --></div>For CSS variables, you can also use the backdrop-brightness-(<custom-property>) syntax:
<div class="backdrop-brightness-(--my-backdrop-brightness) ..."> <!-- ... --></div>This is just a shorthand for backdrop-brightness-[var(<custom-property>)] that adds the var() function for you automatically.
Responsive design
Prefix a backdrop-filter: brightness() utility with a breakpoint variant like md: to only apply the utility at medium screen sizes and above:
<div class="backdrop-brightness-110 md:backdrop-brightness-150 ..."> <!-- ... --></div>Learn more about using variants in the variants documentation.
