Embeddable Widgets with Vite, React, Tailwind 4 & Web Components

A practical walkthrough of building embeddable widgets using React, Tailwind 4, Vite, and Web Components delivered as a single JS file. Two significant browser limitations are uncovered and solved: Tailwind 4's heavy reliance on CSS @property rules which Shadow DOM doesn't fully support, and @font-face declarations not working inside Shadow Roots. The @property issue is addressed with a custom PostCSS plugin (~300 lines) that transforms Tailwind's property registrations into concrete CSS variable declarations scoped to the shadow host. The font issue is handled by a runtime font loader using the FontFace API that attaches fonts to the parent document instead of the Shadow Root.
