Glassmorphism was popularized in 2020 by Apple macOS Big Sur and Microsoft Windows 11. Its core is the backdrop-filter CSS property, which applies graphical filters (like blur) to content behind an element. Unlike regular filter, backdrop-filter only affects the area behind the element.
Glassmorphism is a UI design style creating frosted glass effects through semi-transparent backgrounds, blur, and subtle borders.
Use backdrop-filter: blur() for background blur, with rgba background, semi-transparent border, and subtle box-shadow.
Well-supported in modern browsers. Provide semi-transparent background fallback for unsupported browsers.
Suitable for cards, modals, navbars needing depth. Avoid large areas - excess reduces readability and performance.
1) Avoid backdrop-filter on large elements; 2) Use will-change; 3) Reduce blur radius; 4) Avoid nesting.
