Fine-tune your layout shadows visually

CSS box-shadows are one of the most powerful styling options for adding depth and realism to a web page. However, writing code manually is tedious and requires constant browser reloading to see the results. Our CSS Box Shadow Generator solves this problem by giving you a live canvas where you can adjust offsets, blur, spread, colors, opacity, and even inset shadow states instantly using sliders.

Standard and Webkit support

Modern browsers universally support the standard box-shadow syntax. This generator provides the clean, standard syntax ready for copying directly into your CSS files. Use it to craft cards, buttons, modals, dropdown headers, and premium glassmorphism surfaces.

FAQ

What is the difference between blur and spread?
Blur radius determines how soft/fuzzy the shadow border looks. A larger blur radius yields a larger, softer shadow. Spread radius actually sizes the shadow area before applying blur. Positive values expand the shadow, while negative values shrink it.
What does the "Inset" checkbox do?
By default, box-shadows cast a shadow outside the element. Checking "Inset" casts the shadow inside the box borders, creating an embossed or pressed-in look.
Is there any performance overhead using shadows?
Usually not, but very large blur radiuses on multiple elements can cause slight rendering lag on low-end mobile devices. Use subtle shadows (e.g. 5-15px blur) for optimal performance.
