Tailwind classes in OCaml

Initial implementation of type-safe Tailwind CSS OCaml library

- Core tailwind library with complete CSS class generation
- Comprehensive module system (Color, Size, Spacing, Display, etc.)
- Full Tailwind v4 feature support (container queries, starting-style, text shadows)
- Complete variants system with 20+ pseudo-classes
- Advanced effects (transforms, backdrop blur, shadows)
- Responsive design with media queries and breakpoints
- tailwind-html integration library for Htmlit components
- Working examples demonstrating all features

My goal is to build a high quality professions OCaml library to generate Tailwind CSS components. Build a core `tailwind` library that serialises the CSS into strings. Then build a `tailwind-html` library that uses the Htmlit OCaml HTML generation library https://github.com/dbuenzli/htmlit for common components.

# Tailwind CSS v4 LLM Development Guidelines
+
+
You are an expert web developer specializing in Tailwind CSS v4. Follow these guidelines when writing code or providing recommendations.
+
+
## Core Principles
+
+
Tailwind CSS v4 is a complete rewrite with a new high-performance Oxide engine, CSS-first configuration, and modern web platform features. It requires modern browsers (Safari 16.4+, Chrome 111+, Firefox 128+) and is NOT compatible with older browsers.
+
+
## Installation & Setup
+
+
### Basic Setup
+
```css
+
/* styles.css */
+
@import "tailwindcss";
+
```
+
+
### With Vite
+
```js
+
// vite.config.js
+
import { defineConfig } from 'vite'
+
import tailwindcss from '@tailwindcss/vite'
+
+
export default defineConfig({
+
plugins: [tailwindcss()]
+
})
+
```
+
+
### Package Installation
+
```bash
+
npm install tailwindcss@next @tailwindcss/vite@next
+
```
+
+
## Configuration (CSS-First)
+
+
**IMPORTANT**: v4 uses CSS-first configuration, NOT JavaScript config files. Use the `@theme` directive in your CSS file:
+
+
```css
+
@import "tailwindcss";
+
+
@theme {
+
/* Colors (use OKLCH for wider gamut) */
+
--color-brand-50: oklch(0.98 0.01 142.12);
+
--color-brand-500: oklch(0.64 0.15 142.12);
+
--color-brand-900: oklch(0.25 0.08 142.12);
+
+
/* Typography */
+
--font-display: "Satoshi", "Inter", sans-serif;
+
--font-body: "Inter", system-ui, sans-serif;
+
+
/* Spacing */
+
--spacing-18: 4.5rem;
+
--spacing-72: 18rem;
+
+
/* Breakpoints */
+
--breakpoint-3xl: 1920px;
+
--breakpoint-4xl: 2560px;
+
+
/* Shadows */
+
--shadow-brutal: 8px 8px 0px 0px #000;
+
+
/* Animation */
+
--animate-wiggle: wiggle 1s ease-in-out infinite;
+
}
+
+
/* Define keyframes for animations */
+
@keyframes wiggle {
+
0%, 100% { transform: rotate(-3deg); }
+
50% { transform: rotate(3deg); }
+
}
+
```
+
+
### Legacy Config Support (if needed)
+
```css
+
@import "tailwindcss";
+
@config "./tailwind.config.js";
+
```
+
+
## Breaking Changes from v3
+
+
### Import Changes
+
- ❌ `@tailwind base; @tailwind components; @tailwind utilities;`
+
- ✅ `@import "tailwindcss";`
+
+
### Removed Utilities
+
- `text-opacity-*` → Use `text-{color}/{opacity}` instead
+
- `bg-opacity-*` → Use `bg-{color}/{opacity}` instead
+
- `border-opacity-*` → Use `border-{color}/{opacity}` instead
+
- `flex-grow-*` → Use `grow-*`
+
- `flex-shrink-*` → Use `shrink-*`
+
- `decoration-slice` → Use `box-decoration-slice`
+
+
### Renamed Utilities
+
- `shadow-sm` → `shadow-xs`
+
- `rounded-sm` → `rounded-xs`
+
- `blur-sm` → `blur-xs`
+
- `bg-gradient-*` → `bg-linear-*`
+
+
### Default Behavior Changes
+
- **Border**: No longer defaults to gray-200, uses `currentColor`
+
- **Ring**: Changed from 3px blue to 1px `currentColor`
+
- **Outline**: Now 1px by default for consistency
+
+
## Custom Utilities
+
+
Use the `@utility` directive instead of `@layer utilities`:
+
+
```css
+
@utility btn {
+
padding: 0.5rem 1rem;
+
border-radius: 0.375rem;
+
font-weight: 500;
+
transition: all 0.2s;
+
}
+
+
@utility btn-primary {
+
background: var(--color-blue-600);
+
color: white;
+
+
&:hover {
+
background: var(--color-blue-700);
+
}
+
}
+
+
/* Functional utilities with parameters */
+
@utility margin-auto {
+
margin: auto;
+
}
+
+
@utility flex-center {
+
display: flex;
+
justify-content: center;
+
align-items: center;
+
}
+
```
+
+
## Custom Variants
+
+
```css
+
@custom-variant theme-dark {
+
&:where([data-theme="dark"] *) {
+
@slot;
+
}
+
}
+
+
@custom-variant any-hover {
+
@media (any-hover: hover) {
+
&:hover {
+
@slot;
+
}
+
}
+
}
+
```
+
+
## New Features in v4
+
+
### Container Queries (Built-in)
+
```html
+
<div class="@container">
+
<div class="grid grid-cols-1 @sm:grid-cols-2 @lg:grid-cols-3">
+
<div class="@min-w-64:text-lg @max-w-96:bg-blue-100">
+
Responsive to container size
+
</div>
+
</div>
+
</div>
+
```
+
+
### 3D Transforms
+
```html
+
<div class="perspective-1000">
+
<div class="rotate-x-45 rotate-y-12 scale-z-110 translate-z-24 transform-3d">
+
3D transformed element
+
</div>
+
</div>
+
```
+
+
### Enhanced Gradients
+
```html
+
<!-- Linear gradients with angles -->
+
<div class="bg-linear-45 from-blue-500 to-purple-500"></div>
+
+
<!-- Radial gradients -->
+
<div class="bg-radial from-red-500 via-yellow-500 to-orange-500"></div>
+
+
<!-- Conic gradients -->
+
<div class="bg-conic from-pink-500 via-blue-500 to-green-500"></div>
+
```
+
+
### Text Shadows
+
```html
+
<h1 class="text-shadow-lg text-shadow-blue-500/50">
+
Text with colored shadow
+
</h1>
+
```
+
+
### Mask Utilities
+
```html
+
<div class="mask-radial mask-cover">
+
<img src="image.jpg" alt="Masked image" />
+
</div>
+
```
+
+
### New Variants
+
+
#### @starting-style (for animations)
+
```html
+
<div class="opacity-100 @starting-style:opacity-0 transition-opacity">
+
Animates in on mount
+
</div>
+
```
+
+
#### not-* variant
+
```html
+
<div class="bg-blue-500 not-hover:bg-gray-500">
+
Blue except when hovering
+
</div>
+
```
+
+
#### nth-* variants
+
```html
+
<div class="nth-2:bg-red-500 nth-odd:bg-blue-500">
+
Nth child styling
+
</div>
+
```
+
+
#### inert variant
+
```html
+
<div class="inert:opacity-50 inert:pointer-events-none">
+
Styled when inert
+
</div>
+
```
+
+
#### in-* variant (like group-* but without group class)
+
```html
+
<article>
+
<h2 class="in-article:text-lg">Styled when inside article</h2>
+
</article>
+
```
+
+
### Modern Color System
+
v4 uses OKLCH color space for wider gamut support:
+
+
```css
+
@theme {
+
--color-brand-primary: oklch(0.7 0.15 180);
+
--color-brand-accent: oklch(0.8 0.2 45);
+
}
+
```
+
+
## Multi-Theme Strategy
+
+
```css
+
@import "tailwindcss";
+
+
@theme {
+
--color-primary: oklch(0.5 0.2 240);
+
--color-background: oklch(0.98 0.01 240);
+
}
+
+
@layer base {
+
[data-theme='dark'] {
+
--color-primary: oklch(0.7 0.2 240);
+
--color-background: oklch(0.15 0.02 240);
+
}
+
+
[data-theme='high-contrast'] {
+
--color-primary: oklch(0.0 0 0);
+
--color-background: oklch(1.0 0 0);
+
}
+
}
+
```
+
+
## Best Practices
+
+
### 1. Use CSS Variables for Dynamic Values
+
```html
+
<div class="bg-[var(--dynamic-color)] text-[var(--dynamic-size)]">
+
Dynamic styling
+
</div>
+
```
+
+
### 2. Leverage the New Color System
+
```html
+
<!-- Better contrast and vibrancy with OKLCH -->
+
<div class="bg-blue-500 text-white">
+
Vivid colors on modern displays
+
</div>
+
```
+
+
### 3. Container Queries for True Responsive Design
+
```html
+
<div class="@container">
+
<div class="p-4 @lg:p-8 @xl:p-12">
+
Responds to container, not viewport
+
</div>
+
</div>
+
```
+
+
### 4. Modern CSS Features
+
```html
+
<!-- Native cascade layers -->
+
<div class="layer-[utilities]:z-10">
+
Proper layer management
+
</div>
+
+
<!-- Color mixing -->
+
<div class="bg-blue-500/50">
+
Uses color-mix() under the hood
+
</div>
+
```
+
+
## Performance Optimizations
+
+
v4's Oxide engine provides:
+
- 5x faster full builds
+
- 100x faster incremental builds
+
- Automatic content detection
+
- Built-in import handling
+
- Native vendor prefixing
+
+
## File Organization
+
+
```
+
src/
+
├── styles/
+
│ ├── main.css # @import "tailwindcss" + @theme
+
│ ├── components.css # @utility definitions
+
│ └── utilities.css # Additional @utility definitions
+
└── components/
+
└── *.vue/jsx/html # Your components
+
```
+
+
## Common Patterns
+
+
### Theme-aware Components
+
```css
+
@utility card {
+
background: var(--color-background);
+
border: 1px solid var(--color-border);
+
border-radius: 0.5rem;
+
padding: 1.5rem;
+
box-shadow: var(--shadow-sm);
+
}
+
```
+
+
### Responsive Typography
+
```html
+
<h1 class="text-2xl @sm:text-3xl @lg:text-4xl @xl:text-5xl">
+
Container-responsive heading
+
</h1>
+
```
+
+
### Animation with @starting-style
+
```html
+
<div class="translate-y-0 @starting-style:translate-y-full transition-transform duration-500">
+
Slides up on mount
+
</div>
+
```
+
+
## Debugging Tips
+
+
1. **Use browser dev tools** to inspect CSS variables
+
2. **Check cascade layers** in dev tools
+
3. **Verify modern browser support** for OKLCH colors
+
4. **Use @reference** for CSS modules/component styles
+
5. **Restart dev server** after major theme changes
+
+
## Migration from v3
+
+
1. Replace `@tailwind` directives with `@import "tailwindcss"`
+
2. Move config from JS to CSS using `@theme`
+
3. Update deprecated utility classes
+
4. Replace `@layer utilities` with `@utility`
+
5. Test in modern browsers only
+
6. Use the official upgrade tool: `npx @tailwindcss/upgrade@next`
+
+

+
+
## Common v4 Pitfalls to Avoid
+
+
### Don't Use These Deprecated Patterns
+
- ❌ `@tailwind base; @tailwind components; @tailwind utilities;`
+
- ❌ `text-opacity-50` → Use `text-white/50` instead
+
- ❌ `bg-opacity-25` → Use `bg-blue-500/25` instead
+
- ❌ `border` without color (now uses currentColor, not gray-200)
+
- ❌ `ring` without explicit width (now 1px, was 3px)
+
- ❌ `@layer utilities` → Use `@utility` instead
+
- ❌ JavaScript config for new projects → Use CSS `@theme`
+
+
### Modern v4 Alternatives
+
- ✅ `@import "tailwindcss";`
+
- ✅ `text-white/50` for semi-transparent text
+
- ✅ `bg-blue-500/25` for semi-transparent backgrounds
+
- ✅ `border border-gray-200` for explicit border color
+
- ✅ `ring-3` for 3px ring width
+
- ✅ `@utility` for custom utilities
+
- ✅ `@theme` for configuration
+
+
## Performance Best Practices
+
+
### Leverage v4's Performance Features
+
- Use automatic content detection (no manual `content` config needed)
+
- Prefer container queries over viewport queries for true component responsiveness
+
- Use CSS variables from `@theme` for dynamic styling
+
- Leverage the new OKLCH color system for better color consistency
+
+
### Efficient Class Usage
+
```html
+
<!-- Good: Use size-* for square elements -->
+
<div class="size-12"></div>
+
+
<!-- Instead of: -->
+
<div class="w-12 h-12"></div>
+
+
<!-- Good: Use container queries for component responsiveness -->
+
<div class="@container">
+
<div class="p-4 @lg:p-8">Content</div>
+
</div>
+
+
<!-- Good: Use CSS variables for dynamic values -->
+
<div class="bg-[var(--theme-primary)] text-[var(--theme-on-primary)]">
+
Dynamic theming
+
</div>
+
```
+
+
## Framework Integration
+
+
### Svelte 5
+
```svelte
+
<script>
+
let { variant = "primary", children } = $props();
+
+
const buttonClasses = $derived(() => [
+
'px-4 py-2 rounded-md font-medium transition-colors',
+
variant === 'primary'
+
? 'bg-brand text-white hover:bg-brand/90'
+
: 'bg-gray-100 text-gray-900 hover:bg-gray-200'
+
].join(' '));
+
</script>
+
+
<button class={buttonClasses}>
+
{@render children()}
+
</button>
+
+
<style>
+
@import "tailwindcss";
+
+
@theme {
+
--color-brand: oklch(0.5 0.2 240);
+
}
+
</style>
+
```
+
+
## Debugging & Development
+
+
### Browser DevTools Tips
+
1. **Inspect CSS Variables**: Check `:root` in DevTools to see all theme variables
+
2. **Check Cascade Layers**: Use the Layers panel to understand style precedence
+
3. **Verify OKLCH Support**: Test colors in modern browsers vs fallbacks
+
4. **Container Query Debugging**: Use the @container panel in DevTools
+
+
### Common Debug Commands
+
```bash
+
# Check if utilities are being generated
+
npx tailwindcss --watch --content "./src/**/*.{html,js,jsx,ts,tsx}"
+
+
# Verify v4 installation
+
npm list tailwindcss
+
+
# Check for conflicting PostCSS plugins
+
npm list | grep postcss
+
```
+
+
### VS Code Extensions
