Styling - Horse Trust

Styling Approach

Horse Trust uses Tailwind CSS 4 as the primary styling solution, combined with a custom equestrian-themed design system. All styles are utility-first with custom CSS variables for brand consistency.

Tailwind CSS Configuration

Installation

package.json

{
  "devDependencies": {
    "@tailwindcss/postcss": "^4",
    "tailwindcss": "^4"
  }
}

Global Styles

Location: app/globals.css

app/globals.css

@import url('https://fonts.googleapis.com/css2?family=Public+Sans:wght@300;400;500;600;700;800;900&family=Playfair+Display:ital,wght@0,400..900;1,400..900&display=swap');
@import "tailwindcss";

@theme {
  --color-equestrian-green: #14532d; /* Verde bosque oscuro */
  --color-equestrian-navy: #0f172a;  /* Azul marino profundo */
  --color-equestrian-gold: #C5A059;  /* Dorado lujo */
  --color-equestrian-sand: #fdfbf7;  /* Blanco arena */
  
  --color-background-light: #fdfbf7;
  --color-background-dark: #0f172a;

  /* Tipografías */
  --font-display: "Public Sans", sans-serif;
  --font-serif: "Playfair Display", serif;
}

Custom Color Palette

Brand Colors

The Horse Trust design system uses an equestrian-inspired color palette:

Color Name	CSS Variable	Hex Value	Usage
Equestrian Green	`--color-equestrian-green`	`#14532d`	Primary actions, success states
Equestrian Navy	`--color-equestrian-navy`	`#0f172a`	Headers, dark backgrounds
Equestrian Gold	`--color-equestrian-gold`	`#C5A059`	Accents, luxury details, CTAs
Equestrian Sand	`--color-equestrian-sand`	`#fdfbf7`	Light backgrounds, cards

Using Custom Colors

Tailwind automatically generates utility classes from CSS variables:

// Background colors
<div className="bg-equestrian-navy" />
<div className="bg-equestrian-gold" />
<div className="bg-equestrian-sand" />

// Text colors
<h1 className="text-equestrian-navy" />
<span className="text-equestrian-gold" />

// Border colors
<div className="border border-equestrian-navy" />

// Hover states
<button className="hover:bg-equestrian-gold" />
<a className="hover:text-equestrian-gold" />

Theme Configuration

Root CSS Variables

:root {

}

@media (prefers-color-scheme: dark) {

  }
}

body {
  background: var(--background);
  color: var(--foreground);
  font-family: var(--font-display);
}

Dark Mode Support

Tailwind’s dark mode is configured for automatic theme switching:

// Responsive dark mode classes
<div className="bg-white dark:bg-equestrian-navy" />
<p className="text-slate-900 dark:text-slate-100" />
<header className="bg-white/95 dark:bg-equestrian-navy/95" />

Custom CSS Classes

Hero Gradient

.hero-gradient {
  background: linear-gradient(
    rgba(15, 23, 42, 0.7) 0%, 
    rgba(15, 23, 42, 0.9) 100%
  );
}

Usage:

<div className="absolute inset-0 hero-gradient" />

Luxury Card Hover

.luxury-card-hover {
  @apply transition-all duration-500 ease-out;
}

}

Usage:

<div className="luxury-card-hover group bg-white rounded-lg">

Scrollbar Styling

Custom scrollbar for both light and dark themes:

    scroll-behavior: smooth;
  }

  /* Chrome, Safari, Edge */
  ::-webkit-scrollbar {
    width: 8px;
    height: 8px;
  }

  ::-webkit-scrollbar-track {
    background: #f1f5f9;
  }

  .dark ::-webkit-scrollbar-track {
    background: var(--color-equestrian-navy);
  }

  ::-webkit-scrollbar-thumb {
    background: #1e293b;
    border-radius: 20px;
    border: 2px solid #f1f5f9;
  }

Responsive Design

Breakpoints

Tailwind’s default breakpoints:

Breakpoint	Min Width	Prefix

Medium	768px	`md:`
Large	1024px	`lg:`
X-Large	1280px	`xl:`
2X-Large	1536px	`2xl:`

Responsive Examples

// Responsive text size
<h1 className="text-4xl md:text-6xl lg:text-7xl">
  Heading
</h1>

// Responsive grid
<div className="grid grid-cols-1 md:grid-cols-2 lg:grid-cols-3 gap-8">
  {/* Items */}
</div>

// Responsive padding
<div className="px-4 sm:px-6 lg:px-8">
  {/* Content */}
</div>

// Responsive visibility
<div className="hidden lg:block">
  {/* Desktop only */}
</div>
<div className="block lg:hidden">
  {/* Mobile only */}
</div>

Layout Utilities

Container

<div className="max-w-7xl mx-auto px-4 sm:px-6 lg:px-8">
  {/* Centered content with responsive padding */}
</div>

Flexbox

<div className="flex items-center justify-between gap-6">
  {/* Flex items */}
</div>

<div className="flex flex-col md:flex-row gap-4">
  {/* Responsive flex direction */}
</div>

Grid

<div className="grid grid-cols-2 md:grid-cols-4 lg:grid-cols-6 gap-12">
  {/* Responsive grid */}
</div>

Animation & Transitions

Transition Classes

// Standard transition
<div className="transition-all duration-300 ease-out" />

// Hover transform
<div className="hover:-translate-y-2 transition-transform" />

// Group hover effects
<div className="group">
  <img className="group-hover:scale-110 transition-transform duration-1000" />
  <h4 className="group-hover:text-equestrian-gold transition-colors" />
</div>

Backdrop Effects

// Backdrop blur
<div className="backdrop-blur-md bg-white/10" />

// Backdrop with border
<div className="backdrop-blur-sm bg-white/90 border border-white/20" />

Best Practices

1. Use Semantic Color Names

// Good
<button className="bg-equestrian-gold text-equestrian-navy" />

// Avoid
<button className="bg-[#C5A059] text-[#0f172a]" />

2. Leverage Tailwind’s Utility Classes

// Good
<div className="flex items-center gap-4 p-6 rounded-xl" />

// Avoid inline styles
<div style={{ display: 'flex', padding: '1.5rem' }} />

3. Use Responsive Prefixes

// Mobile-first responsive design
<div className="text-sm md:text-base lg:text-lg" />

4. Group Hover Effects

<div className="group">
  <img className="group-hover:scale-110" />
  <p className="group-hover:text-gold" />
</div>

5. Consistent Spacing

Use Tailwind’s spacing scale (4px increments):

<div className="p-4 mb-6 space-y-8" />
