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.

A propriedade CSS backdrop-filter permite que você aplique efeitos gráficos, como desfoque ou mudança de cores, na área ao fundo de um elemento. Como ela se aplica a tudo que fica atrás do elemento, é preciso deixá-lo (ou o seu plando de fundo) ao menos parcialmente transparente para poder ver o efeito em ação.
