Generate stunning CSS effects visual and fast.
Interactive playground for modern CSS: glassmorphism, multi-layer box shadows, gradients with OKLab interpolation, organic border radius and filters — with the generated code always in view.

Change controls on the left to see modifications in real-time.
ButtonScroll to zoom at the cursor, drag to pan, hold B to compare with the unstyled element.
The PNG is redrawn from the same values on a canvas — not a screenshot — so it stays sharp at any size.

Drop in a box-shadow, gradient, border-radius or filter — even a whole rule — and the controls jump to it.
How it works
Pick an effect
Glass, layered shadow, gradient, radius or filter — five generators sharing one preview.
Tune it
Drag a slider or type the exact number. Every change is one undo away.
Check it
Zoom at the cursor, pan around, and hold to compare against the unstyled element.
Ship it
Copy CSS, Tailwind, SCSS or variables, share a link, or send the PNG straight to another tool.
Multi-layer shadows
Stack as many layers as a real elevation needs, mute any of them, and duplicate the one that already works.
Modern colour spaces
Interpolate gradients in OKLab or OKLCH to kill sRGB banding, and print any value as HEX, RGB, HSL or oklch().
Paste CSS back in
Drop in a rule you already have and the sliders jump to it, instead of rebuilding it by eye.
Organic corners
Eight-point border-radius with a live preset grid, plus a manual field for the exact blob you want.
Cheap undo history
Sixty steps of undo that store the numbers, not the pixels, so nothing eats your memory.
Straight into the next tool
Render the surface to a PNG and send it to CompressSnap, CropSnap or MemeBolt without a download.
Nothing leaves the browser
No upload, no account, no server round trip. Your image never leaves the tab it was dropped into.
Built for the keyboard
Numbers 1–5 switch generator, Ctrl+Z undoes, Alt tunes a slider ten times finer.
Generate stunning CSS effects visual and fast.
Designing modern styles should not mean guessing numbers in a text editor. Five generators share one live preview: tune it with sliders or exact values, compare against the unstyled element, undo anything, and take the result away as code, as a link, or as a PNG.
100% Client-Side Processing
All styles are compiled locally in your browser. No files are uploaded, ensuring instant rendering and complete privacy.
The ultimate CSS companion for frontend devs and UI/UX designers.
Quickly style cards, buttons, backgrounds, and overlay panels. Ideal for Figma-to-code translations, prototyping layouts, and styling modern dashboards.
Your CSS recipes remain private. Everything occurs on your local machine; we do not store, track, or upload your designs.
Frequently Asked Questions
QIs this tool completely free?+
Yes, CSS Designer is 100% free with no registration, premium limits, or watermarks.
QCan I use the generated code directly in Tailwind CSS?+
Yes. We generate standard CSS rules along with utility-class combinations using Tailwind arbitrary values, making copy-pasting seamless.
QWhat is Glassmorphism?+
Glassmorphism is a UI trend that mimics frosted glass. It uses backdrop-filter blur and semi-transparent backgrounds to overlay elements elegantly on colorful backdrops.
QDoes it work on mobile?+
Absolutely. The layout is optimized to work on smartphones, tablets, and desktops so you can code on the go.
QCan I paste a CSS rule I already have?+
Yes. Open "Paste existing CSS" under the code panel and drop in a box-shadow, a gradient, a border-radius or a filter — a whole rule works too. The controls jump to those values so you can keep editing from there.
QWhat does interpolating in OKLab or OKLCH change?+
sRGB interpolation drags the midpoint of a gradient through a grey, muddy zone. OKLab and OKLCH keep perceived lightness even, so a violet-to-pink blend stays vivid all the way across. The generated CSS uses the standard "in oklab" syntax.
QIs the PNG export a screenshot?+
No. The image is redrawn on a canvas from the same numbers the preview uses, so it is sharp at 1600×900 or 1080×1920 and you can send it straight to another oLoveTools tool without downloading it.
QDoes anything get uploaded when I add my own image?+
No. The image is decoded in the tab and only used as a backdrop for the preview. Even the palette extraction runs on your machine, and only when you press the button.
