Frequently Asked Questions
What CSS properties create the glassmorphism effect?
The core effect is created using 'backdrop-filter: blur(...)', a semi-transparent background color (rgba or hsla), a subtle border stroke with white/alpha tint, and soft box-shadows.
Why is -webkit-backdrop-filter included in the code?
Safari and iOS WebKit require the '-webkit-' prefix for backdrop-filter to render properly. Including both ensures full cross-browser compatibility across Chrome, Safari, and Firefox.
Does glassmorphism work on solid white or solid black backgrounds?
Glassmorphism looks best when placed over colorful, patterned, or image backgrounds because the blur effect requires underlying visual textures to refract and distort.
