What is the purpose of the backdrop-filter property and how can it create glassmorphism?

Asked on Sep 21, 2025

Answer

The `backdrop-filter` property in CSS is used to apply graphical effects like blurring or color shifting to the area behind an element, creating a translucent effect that is key to achieving the glassmorphism design style.

Example Concept: The `backdrop-filter` property allows you to apply effects such as blurring or color adjustments to the background of an element. This is particularly useful in creating glassmorphism, where elements appear as frosted glass by using effects like `blur()`. When combined with semi-transparent backgrounds, it gives the impression of looking through a glass pane.

Additional Comment:

The `backdrop-filter` property requires the element to have a background with some transparency (e.g., rgba or hsla colors).
Common effects include `blur()`, `brightness()`, `contrast()`, `grayscale()`, and `sepia()`.
Ensure browser compatibility as not all browsers fully support `backdrop-filter`.
Use `backdrop-filter` judiciously to maintain performance, especially on complex pages.
