Since â¨September 2024â©, 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.
