Release Notes

tailwindlabs/tailwindcss (tailwindcss)

v4.3.3

Compare Source

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 earlier @source rules pointing to nested files are scanned when later @source rules point to files in parent folders (#​20335)
  • Prevent @tailwindcss/vite from triggering full page reloads when scanned files are processed by Vite but haven't been loaded as modules yet (#​20336)

v4.3.2

Compare Source

Fixed
  • Support bare spacing values for auto-rows-* and auto-cols-* utilities (e.g. auto-rows-12 and auto-cols-16) (#​20229)
  • Prevent @tailwindcss/cli in --watch mode from crashing on Windows when @source points to a directory that doesn't exist (#​20242)
  • Prevent @tailwindcss/vite from crashing in Deno v2.8.x when context.parentURL is not a valid URL (#​20245)
  • Ensure @tailwindcss/cli in --watch mode rebuilds when the input CSS file changes in an ignored directory (#​20246)
  • Allow @variant rules used in addBase(…) to use custom variants defined later (#​20247)
  • Prevent @tailwindcss/vite from crashing during HMR when scanned files or directories are deleted (#​20259)
  • Generate font-size instead of color declarations for text-[--spacing(…)] (#​20260)
  • Prevent @source patterns from scanning unrelated sibling files and folders (#​20263)
  • Extract class candidates adjacent to Template Toolkit delimiters like %]…[% in .tt, .tt2, and .tx files (#​20269)
  • Extract class candidates from conditional Maud syntax like p.text-black[condition] (#​20269)
  • Prevent @position-try rules from triggering unknown at-rule warnings when optimizing CSS (#​20277)
  • Support class suggestions for named opacity modifiers from --opacity theme values (#​20287)
  • Prevent type errors in @tailwindcss/postcss when used with newer PostCSS patch releases (#​20289)

Fixed
  • Remove deprecation warnings by using Module#registerHooks instead of Module#register on Node 26+ (#​20028)
  • Canonicalization: don't crash when plugin utilities throw for unsupported values (#​20052)
  • Allow @apply to be used with CSS mixins (#​19427)
  • Ensure not-* correctly negates @container queries, including style(…) queries (#​20059)
  • Ensure drop-shadow-* color utilities work with custom shadow values containing calc(…) (#​20080)
  • Fix 'Sourcemap is likely to be incorrect' warnings when using @tailwindcss/vite (#​20103)
  • Ensure @tailwindcss/webpack can be installed in Rspack projects without requiring webpack as a peer dependency (#​20027)
  • Canonicalization: don't suggest invalid calc(…) expressions (e.g. px-[calc(1rem+0px)]px-[calc(1rem+0)]) (#​20127)
  • Canonicalization: avoid suggesting large spacing-scale values for arbitrary lengths (e.g. left-[99999px]left-[99999px], not left-24999.75) (#​20130)
  • Ensure @tailwindcss/cli in --watch mode recovers when a tracked dependency is deleted and restored (#​20137)
  • Ensure standalone @tailwindcss/cli binaries are ignored when scanning for class candidates (#​20139)
  • Ensure class candidates are extracted from Twig addClass(…) and removeClass(…) calls (#​20198)
  • Don't crash in the Ruby or Vue preprocessors when scanning files containing invalid UTF-8 bytes (#​19588)
  • Allow @variant to be used inside addBase (#​19480)
  • Ensure @source globs with symlinks are preserved (#​20203)

  • Ensure explicitly referenced @source directories are scanned even when ignored by git (#​20214)
  • Ensure @source globs ending in **/* preserve dynamic path segments to avoid scanning too many files (#​20217)
  • Canonicalization: don't fold calc(…) divisions when the result would require high precision (e.g. w-[calc(100%/3.5)]w-[calc(100%/3.5)], not w-[28.571428571428573%]) (#​20221)
  • Serve ESM type declarations to ESM importers of @tailwindcss/postcss (#​20228)
Changed
  • Generate 0 instead of calc(var(--spacing) * 0) for spacing utilities like m-0 and left-0 (#​20196)
  • Generate var(--spacing) instead of calc(var(--spacing) * 1) for spacing utilities like m-1 and left-1 (#​20196)
