Why use multi-layer box shadows instead of a single shadow?

Single shadows look flat and harsh. Layering 2 to 4 soft, low-opacity shadows mimics real-world ambient lighting, creating natural 3D depth and smooth elevation.

What is Glassmorphism and how does it work?

Glassmorphism is a UI trend that creates semi-transparent frosted glass panels using CSS backdrop-filter: blur() combined with subtle borders and low-opacity backgrounds.

Are backdrop-filter effects supported across all modern browsers?

Yes! Modern versions of Chrome, Safari, Firefox, and Edge fully support backdrop-filter: blur(). Safari requires the -webkit-backdrop-filter vendor prefix which is included in the exported code.

Is this service free?

Does the site store my data?

No. All your data is stored locally in your own browser for your convenience and is never sent to any external server or database.
