Bumps tailwindcss from 4.2.2 to 4.3.0.

Release notes

Sourced from tailwindcss's releases.

v4.3.0

Added

  • Add @container-size utility (#18901)
  • Add scrollbar-{auto,thin,none} utilities for scrollbar-width, and scrollbar-thumb-* / scrollbar-track-* color utilities for scrollbar-color (#19981, #20019)
  • Add scrollbar-gutter-* utilities (#20018)
  • Add zoom-* utilities (#20020)
  • Add tab-* utilities (#20022)
  • Allow using @variant with stacked variants (e.g. @variant hover:focus { … }) (#19996)
  • Allow using @variant with compound variants (e.g. @variant hover, focus { … }) (#19996)
  • Support --default(…) in --value(…) and --modifier(…) for functional @utility definitions (#19989)

Fixed

  • Ensure @plugin resolves package JavaScript entries instead of browser CSS entries when using @tailwindcss/vite (#19949)
  • Fix relative @import and @plugin paths resolving from the wrong directory when using @tailwindcss/vite (#19965)
  • Ensure CSS files containing @variant are processed by @tailwindcss/vite (#19966)
  • Resolve imports relative to base when result.opts.from is not provided when using @tailwindcss/postcss (#19980)
  • Canonicalization: preserve significant _ whitespace in arbitrary values (#19986)
  • Canonicalization: add parentheses when removing whitespace from arbitrary values would hurt readability (e.g. w-[calc(100%---spacing(60))] → w-[calc(100%-(--spacing(60)))]) (#19986)
  • Canonicalization: preserve the original unit in arbitrary values instead of normalizing to base units (e.g. -mt-[20in] → mt-[-20in], not mt-[-1920px]) (#19988)
  • Canonicalization: migrate arbitrary :has() variants from [&:has(…)] to has-[…] (#19991)
  • Upgrade: don’t migrate inline style attributes (e.g. style="flex-grow: 1" → style="flex-grow: 1", not style="grow: 1") (#19918)
  • Allow multiple @utility definitions with the same name but different value types (#19777)
  • Export missing PluginWithConfig type from tailwindcss/plugin to fix errors when inferring plugin config types (#19707)
  • Ensure start and end legacy utilities without values do not generate CSS (#20003)
  • Ensure --value(…) is required in functional @utility definitions (#20005)
  • Canonicalization: preserve required whitespace around operators in negated arbitrary values (e.g. -left-[(var(--a)+var(--b))]) (#20011)

v4.2.4

Fixed

  • Ensure imports in @import and @plugin still resolve correctly when using Vite aliases in @tailwindcss/vite (#19947)

v4.2.3

Fixed

  • Canonicalization: improve canonicalizations for tracking-* utilities by preferring non-negative utilities (e.g. -tracking-tighter → tracking-wider) (#19827)
  • Fix crash due to invalid characters in candidate (exceeding valid unicode code point range) (#19829)
  • Ensure query params in imports are considered unique resources when using @tailwindcss/webpack (#19723)
  • Canonicalization: collapse arbitrary values into shorthand utilities (e.g. px-[1.2rem] py-[1.2rem] → p-[1.2rem]) (#19837)
  • Canonicalization: collapse border-{t,b}-* into border-y-*, border-{l,r}-* into border-x-*, and border-{t,r,b,l}-* into border-* (#19842)
  • Canonicalization: collapse scroll-m{t,b}-* into scroll-my-*, scroll-m{l,r}-* into scroll-mx-*, and scroll-m{t,r,b,l}-* into scroll-m-* (#19842)
  • Canonicalization: collapse scroll-p{t,b}-* into scroll-py-*, scroll-p{l,r}-* into scroll-px-*, and scroll-p{t,r,b,l}-* into scroll-p-* (#19842)
  • Canonicalization: collapse overflow-{x,y}-* into overflow-* (#19842)
  • Canonicalization: collapse overscroll-{x,y}-* into overscroll-* (#19842)
  • Read from --placeholder-color instead of --background-color for placeholder-* utilities (#19843)
  • Upgrade: ensure files are not emptied out when killing the upgrade process while it's running (#19846)
  • Upgrade: use config.content when migrating from Tailwind CSS v3 to Tailwind CSS v4 (#19846)
  • Upgrade: never migrate files that are ignored by git (#19846)
