When using CSS glass effect, it is very important to set the background color, blur and opacity. If it is not balanced properly, its glass feeling may not be seen as expected in the web page.

There is a growing tendency from big companies to use glassmorphism in their designs. Apple and Microsoft are some examples using this method in their user interfaces. There are many applications of glass effect on Windows 11 UI. There is a similar trend called "Neumorphism", but unlikely, glassmorphism increases its impact day by day as it looks very professional if you use it properly. It is not advised to use this effect on your whole design since excessive usage may lead to bad user experience.

For increasing the look of the effect, you can use a transparent border which has the same color with the glass. It makes the edges shiny and completes the overall look in a nice way.

Here, you can see an example for the CSS glass effect and the difference between the applied background versus raw background. Also, you can check Dribble to see the examples of CSS glassmorphism.

CSS Frosted Glass Effect by Using Background Blur

How to use Online CSS Glassmorphism Generator?

You can create your own CSS glass effects by following these steps.

1. First, you need to select glass color. It is advised to use white color on dark backgrounds and black color on light backgrounds, but you can use any color according to your needs.
2. Then, you must set blur and transparency. When you increase the amount of blur, it increases the frostiness of the glass effect. If you want to use any text on the glass effect, it is a good practice to use high opacity values and decrease transparency. But keep in mind that, if the opacity is too high, it becomes hard to see the effect at some point.
3. You can both use an image or shapes for previewing the glass effect. Also, you can shuffle both glass color and background image to check different combinations.
4. "Copy CSS" button can be used to get the CSS code and paste to your project.

Frequently asked questions

How does the frosted-glass effect work?

Mostly one property. backdrop-filter: blur() blurs whatever sits behind the element rather than the element itself, and a semi-transparent background plus a light border sells the rest of the illusion.

Why does it look like nothing is happening?

Almost always because there is nothing behind it to blur. Glassmorphism needs something visually busy underneath — a photo, a gradient, overlapping shapes. Over a flat colour the effect is invisible by definition.

Is it supported everywhere?

In current browsers, yes, though Firefox was late to it and some older versions need the effect to degrade gracefully. A sensible fallback is a slightly more opaque background with no blur.

Does it hurt performance?

It can. backdrop-filter forces the browser to re-composite what is behind the element, which is noticeable if you apply it to many elements or animate it. One or two panels is fine; a grid of twenty is not.

What should sit behind it?

Something with colour and movement in it. The CSS Gradient Generator and the SVG Blob Generator both make good backdrops for it.
