About CSS Generator
CSS Generator is a browser-based visual builder for the CSS properties designers reach for most: gradients, box + text shadows, borders, border-radius, filters, transforms, flexbox, grid, and animations. Adjust sliders and pickers on the left, watch the preview react live in the middle, and copy the generated code from the dark panel on the right.
Every builder emits idiomatic modern CSS — the same shape you'd write by hand — so you can paste directly into your stylesheet, component library, or CMS. No proprietary syntax, no vendor prefixes, no signup.
100% client-side: the generator runs entirely in your browser. Nothing is uploaded.

Key Features
10 property builders
Gradient — linear / radial / conic with up to 5 stops. Box shadow — multi-shadow with x/y/blur/spread/inset. Text shadow — same model, applied to text. Border — uniform or per-side. Radius — corner control. Filter — blur, brightness, contrast, saturate, grayscale, sepia, hue-rotate, invert, opacity. Transform — translate, rotate, scale, skew. Flex and Grid layout controls with animated child previews. Animation — preset keyframes with duration/timing/iteration.
Live preview
Every adjustment updates the preview instantly. See the exact rendered result before you copy the code.
Copy-ready CSS
Output uses standard modern CSS syntax — no vendor prefixes, no obsolete fallbacks. Paste directly into any stylesheet.
Multi-shadow support
Add multiple box shadows or text shadows in one property, each with its own offsets and color. Great for layered depth or neon glow effects.
Flex + Grid with real children
Adjust the number of preview children with a slider — see how justify/align/gap changes affect a real layout, not an abstract diagram.
Animation with live-running preview
Pick from 7 preset keyframes (bounce, pulse, spin, shake, slide, fade, wobble). The preview animates while you tweak duration, delay, timing, and iteration.
