backdrop-filter

Baseline 2024

Newly available

Since September 2024, this feature works across the latest devices and browser versions. This feature might not work in older devices or browsers.

La propiedad CSS backdrop-filter le permite aplicar efectos gráficos como desenfoque o cambio de color al área detrás de un elemento. Debido a que se aplica a todo lo que hay detrás del elemento, para ver el efecto debe hacer que el elemento o su fondo sean al menos parcialmente transparentes.
