name: theme-styling description: Apply consistent theming with Tailwind CSS 4, including dark mode support and design tokens. Use when styling components, fixing dark mode issues, or adjusting visual design.

Theme Styling

Apply consistent styling using Tailwind CSS 4 and the project's theme system.

Tailwind CSS 4

This project uses Tailwind CSS 4, which has significant changes from v3:

  • Uses @theme directive instead of theme() function
  • PostCSS config uses @tailwindcss/postcss
  • CSS variables defined in :root and .dark

Theme System

Colors are defined using CSS custom properties in site/src/index.css:

:root {
  --background: oklch(0.97 0.01 85);
  --foreground: oklch(0.20 0.02 250);
  /* ... more tokens */
}

.dark {
  --background: oklch(0.14 0.02 260);
  --foreground: oklch(0.93 0.01 260);
  /* ... more tokens */
}

See references/color-tokens.md for the complete token list.

Using Theme Colors

Always use semantic color names, not raw values:

// Good - uses theme tokens
<div className="bg-background text-foreground">
<div className="bg-card text-card-foreground">
<div className="border-border">
<button className="bg-primary text-primary-foreground">

// Bad - hardcoded colors
<div className="bg-white text-gray-900">
<div className="bg-[#1a1a2e]">

Dark Mode

Dark mode is implemented via the .dark class on the <html> element.

Adding Dark Mode Styles

Use the dark: variant for dark mode overrides:

// Automatic - uses CSS variables that change with theme
<div className="bg-background text-foreground">

// Manual override - when you need different behavior
<div className="bg-white dark:bg-gray-900">

Testing Dark Mode

  1. Toggle with the theme switcher in the nav
  2. Or use browser DevTools to add/remove .dark class on <html>

Spacing & Layout

Use consistent spacing from the Tailwind scale:

ClassSize
p-20.5rem (8px)
p-41rem (16px)
p-61.5rem (24px)
p-82rem (32px)

Mobile-First Responsive

Always start with mobile styles, then add larger breakpoints:

// Good - mobile first
<div className="p-4 md:p-6 lg:p-8">
<div className="grid-cols-1 md:grid-cols-2 lg:grid-cols-3">

// Bad - desktop first
<div className="p-8 sm:p-6 xs:p-4">

Typography

Use the system font stack (already configured):

<h1 className="text-3xl font-bold">       // 30px bold
<h2 className="text-2xl font-semibold">   // 24px semibold
<h3 className="text-xl font-medium">      // 20px medium
<p className="text-base">                 // 16px regular
<span className="text-sm text-muted-foreground">  // 14px muted

Interactive States

Use consistent state styles:

<button className="
  bg-primary text-primary-foreground
  hover:bg-primary/90
  focus-visible:ring-2 focus-visible:ring-ring
  disabled:opacity-50 disabled:pointer-events-none
">

Animations

Use tw-animate-css for animations (already imported):

<div className="animate-fade-in">
<div className="animate-slide-up">

For custom transitions:

<div className="transition-colors duration-200">
<div className="transition-transform duration-300 hover:scale-105">

The cn() Helper

Always use cn() from @/lib/utils for conditional classes:

import { cn } from '@/lib/utils'

<div className={cn(
  'base-styles',
  isActive && 'active-styles',
  className  // allow overrides via props
)}>

Common Patterns

Card

<div className="bg-card text-card-foreground rounded-lg border border-border p-6">

Section

<section className="py-12 md:py-16 lg:py-20">

Button (Primary)

<button className="
  px-4 py-2 rounded-md
  bg-primary text-primary-foreground
  hover:bg-primary/90
  focus-visible:outline-none focus-visible:ring-2 focus-visible:ring-ring
">

Checklist

Before considering styling complete:

  • Uses semantic color tokens (bg-background, not bg-white)
  • Works in both light and dark modes
  • Mobile-first responsive design
  • Uses cn() for conditional classes
  • Interactive elements have hover/focus states
  • Spacing follows Tailwind scale (p-4, p-6, etc.)
