What’s a modern website really without a couple of backdrop blurs? Keep stacking filters until your designer politely begs you to please stop.
Working late and want to spare your eyes? Just drop dark: before any color and it takes over the instant things go dark.
Tweaking your theme is as easy as defining a couple of CSS variables.
@theme { --font-sans: "Inter", sans-serif; --font-mono: "IBM Plex Mono", monospace; --text-tiny: 0.625rem; --text-tiny--line-height: 1.5rem; --color-mint-100: oklch(0.97 0.15 145); --color-mint-200: oklch(0.92 0.18 145); --color-mint-300: oklch(0.85 0.22 145); --color-mint-400: oklch(0.78 0.25 145); --color-mint-500: oklch(0.7 0.28 145); --color-mint-600: oklch(0.63 0.3 145); --color-mint-700: oklch(0.56 0.32 145); --color-mint-800: oklch(0.48 0.35 145); --color-mint-900: oklch(0.4 0.37 145); --color-mint-950: oklch(0.3 0.4 145);}The whole palette now reaches into punchier wide gamut colors, and you reap the benefit without ever knowing what that means.
Dropping grid utilities straight into your HTML makes even the gnarliest layouts easy to reason about.

Breezel builds on CSS layers so specificity fights are no longer your concern.
@layer theme, base, components, utilities;@layer theme { :root { /* Your theme variables */ }}@layer base { /* Preflight styles */}@layer components { /* Your custom components */}@layer utilities { /* Your utility classes */}Supporting text that flows in either direction is finally painless.
Mark any element as a container so its children can respond to its size instead.
<div class="@container"> <div class="grid grid-cols-1 @sm:grid-cols-2"> <img src="/img/photo-1.jpg" class="aspect-square @sm:aspect-3/2 object-cover" /> <img src="/img/photo-2.jpg" class="aspect-square @sm:aspect-3/2 object-cover" /> <img src="/img/photo-3.jpg" class="aspect-square @sm:aspect-3/2 object-cover" /> <img src="/img/photo-4.jpg" class="aspect-square @sm:aspect-3/2 object-cover" /> </div></div>Skip the tangled gradient syntax entirely and paint buttery-smooth gradients with nothing more than a few utility classes.
Rethinking what real-time means
Our brand-new rendering engine delivers speed and efficiency you can actually feel, giving builders the freedom to push past limits they used to accept.
Two dimensions can feel flat. Scale, rotate, and translate any element through 3D space to give the page a real sense of depth.
Ship faster and smaller.
Breezel automatically strips out every unused style when building for production, which means your final CSS bundle ends up as small as it could possibly be. In fact, most Breezel projects ship less than 10kB of CSS to the browser.
<!DOCTYPE html><html lang="en"> <head> <meta charset="UTF-8" /> <meta name="viewport" content="width=device-width, initial-scale=1.0" /> <title>Breezel CSS</title> <link rel="stylesheet" href="/build.css" /> </head> <body> <button class=""></button> </body></html>@layer utilities {}Build whatever you want, without touching your CSS file.
Because Breezel is so low-level, it never nudges you toward designing the same site twice. Plenty of the sites you already love are built with Breezel, and you almost certainly never noticed.
Move even faster with Breezel Plus.
Breezel Plus is a curated set of gorgeous, fully responsive UI components, crafted and maintained by us, the team behind Breezel CSS. It packs hundreds of ready-to-drop examples to pick from, and is sure to give you the ideal launching pad for whatever it is you happen to be building.
