easeUI

Theme setup

Every easeUI component reads from the same small set of design tokens. Add them once and each component you install looks and moves the way it should.

1

Already using shadcn

Your project already has the tokens. If you have not run init yet, do it once and it adds them to your CSS.

npx shadcn@latest init

Starting without shadcn

Paste the stylesheet below into globals.css, right after @import "tailwindcss";. It needs Tailwind CSS v4. You can also open the raw file.

What the tokens cover

  • ColorBackground, foreground, card, border, and accent values that flip between light and dark mode.
  • MotionThe ease-out and ease-in-out curves every easeUI animation is tuned against.
  • UtilitiesSmall helpers like hidden scrollbars and fade masks that a few components rely on.
