This is an experimental technology
Check the Browser compatibility table carefully before using this in production.

Draft
This page is not complete.

The prefers-reduced-transparency CSS media feature is used to detect if the user has requested that the system minimize the amount of transparency used across elements.

Syntax

no-preference
Indicates that the user has made no preference known to the system. This keyword value evaluates as false in the boolean context.
reduce
Indicates that user has notified the system that they prefer an interface that minimizes the amount of transparent or translucent layer effects.

User preferences

Currently no user agent implements this feature, although various operating systems do support such preferences and if this media query is ever implemented user agents will likely rely on the settings provided by the operating systems.

Examples

Note: No browser currently implements this feature so the following example will not work.

This example has an annoying transparency effect by default.

HTML

<div class="transparency">transparent box</div>

CSS

.transparency {
  opacity: 0.5; 
}

@media (prefers-reduced-transparency: reduce) {
  .transparency {
    opacity: 1;
  }
}
