Release Notes

tailwindlabs/tailwindcss (@​tailwindcss/cli)

v4.3.0

Compare Source

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)

Note

Low Risk
Patch/minor dependency bump with no code changes; main risk is visual or build regressions from Tailwind 4.3.0, which should be caught by existing CSS/build and test runs.

Overview
Bumps the Tailwind CSS v4 stack from 4.2.4 to 4.3.0 in package.json and package-lock.json: tailwindcss, @tailwindcss/cli, and @tailwindcss/postcss. The lockfile also picks up related transitive updates (e.g. @tailwindcss/node / @tailwindcss/oxide, enhanced-resolve, tapable, and wasm optional deps).

There are no application or style source changes in this diff—only dependency versions. v4.3.0 adds utilities (@container-size, scrollbar, zoom-*, tab-*, etc.) and fixes around Vite/Postcss resolution and arbitrary-value canonicalization; those only matter if you adopt new classes or hit the fixed edge cases after upgrading.
