What is Glassmorphism in Web Design?

Have you ever seen a website design that looks like a beautiful piece of frosted glass floating over a colorful background? That style is called Glassmorphism.

It has become super popular in modern apps because it looks sleek, premium, and clean. In this guide, we will break down what it is and how to make it yourself in simple words.

The 4 Rules of Glassmorphism

To make a card look like frosted glass, you need to combine four simple ingredients:

• Transparency: You need to be able to see the background colors glowing through the card (using colors with opacity like rgba(255, 255, 255, 0.4)).
• Blur (Backdrop Filter): This is the magic step. By adding a blur effect behind the transparent card, the background colors blend together, mimicking real frosted glass.
• Thin Border: A very subtle white border outlines the card, defining its shape and pretending to catch light.
• Vibrant Backgrounds: Glassmorphism only works if you have colorful shapes or gradients behind it. On a plain white or gray background, the effect gets lost!
