Twelve tools, no signup, no nonsense

SleekCSS is a small set of free, interactive CSS generators for effects developers rebuild constantly: frosted glass panels, layered box shadows, gradient text, fluid type with clamp, grid layouts, triangles and arrows, cubic-bezier easing curves, clip-path shapes, button hover states, 3D transforms, and color palettes.

Why this exists

Looking up the exact syntax for a multi-layer box-shadow or a cubic-bezier curve takes longer than it should, and most generators either bury the output behind an account wall or don't let you see the effect update live as you adjust it. SleekCSS is built the opposite way: every panel on the site is a real, working instance of the tool it's demonstrating, and the CSS output updates as you move the sliders — no login, no rate limit, no paywall.

How it's built

Every tool runs entirely in your browser. There's no server processing your input and no account system — the page you load is the entire application. That also means nothing you type or drag into a generator is ever sent anywhere; it's just JavaScript updating the DOM on your own device.

Who's behind it

SleekCSS is an independently built and maintained set of tools, made because I kept needing exactly this and couldn't find a version that didn't feel like it was built for someone else's workflow. If something's broken or missing, the contact page is the fastest way to reach me.
