winget install --id TailwindLabs.TailwindCSSAbout Tailwind CSS
Tailwind CSS works by scanning all of your HTML files, JavaScript components, and any other templates for class names, generating the corresponding styles and then writing them to a static CSS file. It's fast, flexible, and reliable — with zero-runtime.
What's new in 4.3.3
Fixed - Support --watch --poll[=ms] in @tailwindcss/cli when filesystem events are unreliable or unavailable (#20297) - Canonicalization: match arbitrary hex colors against theme colors case-insensitively (e.g. bg-[#fff] and bg-[#FFF] → bg-white) (#20298) - Prevent Preflight from overriding Firefox's native iframe:focus-visible outline styles (#20292) - Ensure theme('colors.foo') in JS plugins resolves correctly when both --color-foo and --color-foo-bar exist (#20299) - Ensure fractional opacity modifiers work with named shadow sizes like shadow-sm/12.5, text-shadow-sm/12.5, drop-shadow-sm/12.5, and inset-shadow-sm/12.5 (#20302) - Parse selectors like [data-foo]div as two selectors instead of one (#20303) - Ensure @tailwindcss/postcss rebuilds when a preprocessor like Sass changes the input CSS without changing the input file on disk (#20310) - Ensure CSS nesting is handled even when Lightning CSS isn't run, such as in @tailwindcss/browser and Tailwind Play (#20124) - Prevent achromatic theme colors from shifting hue when mixed in polar color spaces like oklch (#20314) - Ensure --spacing(0) is optimized to 0px instead of 0 so it remains a <length> when used in calc(…) (#20319) - Load @parcel/watcher only when needed in @tailwindcss/cli --watch mode, so one-off builds and --watch --poll work when @parcel/watcher can't be loaded (#20325) - Use explicit platform fonts instead of system-ui and ui-sans-serif so CJK text respects the page's lang attribute on Windows (#20318) - Prevent @tailwindcss/upgrade from rewriting ignored files when run from a subdirectory (#20329) - Ensure...
