A themeable starting point for every project. CSS custom properties, a consistent token system, and full light & dark mode support — so you can focus on what makes your product unique.
All form input types shown below. Validation fires only after you interact with a field, never on page load.
Everything you need to know to get up and running. Can't find what you're looking for? Reach out to us.
Design tokens are named variables that store visual design decisions —
colors, spacing, typography, and more. Instead of hard-coding
#3b82f6 across hundreds of files, you reference
--color-accent once. When you rebrand or tweak a theme,
you change one variable and every component updates automatically.
The semantic color tokens use the CSS light-dark() function,
which automatically resolves to the correct value based on the
color-scheme declared on :root. The browser reads
the user's system preference and switches the active scheme for you —
no prefers-color-scheme media queries or class toggling needed.
To add a manual toggle later, just set data-theme on
<html>.
oklch is a perceptually uniform color space, which means that stepping from shade 400 to shade 600 looks like an equal visual jump — unlike hex or hsl where the same numerical step can look very different depending on the hue. This gives you a more predictable and accessible color palette, especially when generating tints and shades programmatically.
Yes. Tokens defined inside @theme are automatically picked
up by Tailwind v4 and turned into utility classes — for example
--color-primary-500 becomes bg-primary-500 and
text-primary-500. For semantic tokens on :root
(like --color-canvas), use Tailwind v4's CSS variable shorthand:
bg-(--color-canvas).
Change the hue angle on the --color-primary-* scale inside
@theme in style.css. The entire scale is built
on a single oklch hue (currently 250 — a blue-violet).
Swap that to 145 for green, 25 for red, or any
angle you need. The semantic --color-accent tokens
automatically inherit the updated brand color.
Every visual decision lives in one of these tokens. Change a value here and the whole UI updates.
