​
Theme Customization Overview

PreLaunch is built with customization in mind, allowing you to easily adjust the visual appearance to match your brand identity. The template uses Tailwind CSS and DaisyUI for styling, providing a robust foundation for customization.

​
Color Scheme Customization

​
Primary Color

The easiest way to customize the color scheme is by changing the primary color in config.ts: 
// config.ts
colors: {
  // The DaisyUI theme to use (leave blank for default light & dark mode)
  theme: "",
  // Primary color used throughout the application
  main: "#3b82f6", // Default blue, change to your brand color
},
This primary color is used for buttons, links, and accent elements throughout the application.

​
Full Theme Customization

For more comprehensive theme customization, you can edit the Tailwind configuration in tailwind.config.js: 
// tailwind.config.js
module.exports = {
  theme: {
    extend: {
      colors: {
        // Add custom colors here
        primary: {
          50: '#f0f9ff',
          100: '#e0f2fe',
          // ... other shades
          600: '#0284c7',
          700: '#0369a1',
        },
        secondary: {
          // Your secondary color palette
        },
        // Add more color palettes as needed
      },
    },
  },
  // Other Tailwind configuration...
};

​
DaisyUI Themes

PreLaunch uses DaisyUI for theming, which provides several pre-built themes. You can select a theme in config.ts: 
// config.ts
colors: {
  // The DaisyUI theme to use
  theme: "light", // Options: "light", "dark", "cupcake", "bumblebee", etc.
  // ...
},
To use a custom DaisyUI theme, modify the tailwind.config.js file: 
// tailwind.config.js
module.exports = {
  // ...
  daisyui: {
    themes: [
      {
        mytheme: {
          "primary": "#4f46e5",
          "secondary": "#f59e0b",
          "accent": "#37cdbe",
          "neutral": "#3d4451",
          "base-100": "#ffffff",
          // ... more color customizations
        },
      },
      "light", // Include other themes you want to use
      "dark",
    ],
  },
  // ...
};
Then reference your custom theme in config.ts: 
// config.ts
colors: {
  theme: "mytheme", // Your custom theme name
  // ...
},

​
Dark Mode / Light Mode

PreLaunch automatically supports dark and light modes. The default configuration includes both modes and automatically switches based on user preferences.

​
Controlling Dark Mode

You can customize how dark mode works by modifying the tailwind.config.js file: 
// tailwind.config.js
module.exports = {
  // ...
  darkMode: 'class', // or 'media' for OS preference-based switching
  // ...
};

​
Customizing Dark Mode Appearance

The dark mode appearance can be customized by using Tailwind’s dark mode variant: 
<div className="bg-white dark:bg-gray-800 text-black dark:text-white">
  This text will be black on white in light mode, and white on dark gray in dark mode.
</div>

​
Typography Customization

​
Font Family

To change the font family, update the tailwind.config.js file: 
// tailwind.config.js
const defaultTheme = require('tailwindcss/defaultTheme');

module.exports = {
  theme: {
    extend: {
      fontFamily: {
        sans: ['Inter', ...defaultTheme.fontFamily.sans],
        heading: ['Montserrat', ...defaultTheme.fontFamily.sans],
        // Add more custom font families as needed
      },
    },
  },
  // ...
};
Then add the font imports to your CSS or update the font links in your HTML head.

​
Font Sizes

Customize font sizes in tailwind.config.js: 
// tailwind.config.js
module.exports = {
  theme: {
    extend: {
      fontSize: {
        'xs': '0.75rem',
        'sm': '0.875rem',
        'base': '1rem',
        'lg': '1.125rem',
        'xl': '1.25rem',
        '2xl': '1.5rem',
        // Add custom sizes as needed
      },
    },
  },
  // ...
};

​
Component Styling

​
Button Styling

PreLaunch includes several button components that can be easily customized. To modify the default button styling, edit the respective component file: 
// components/ui/Button.tsx
// Look for the className definition
const buttonClasses = classNames(
  'inline-flex items-center justify-center rounded-md font-medium transition-colors',
  'focus:outline-none focus:ring-2 focus:ring-offset-2 focus:ring-primary-500',
  {
    'px-4 py-2 text-sm': size === 'default',
    'px-3 py-1.5 text-xs': size === 'small',
    'px-5 py-2.5 text-base': size === 'large',
    // Add your custom variants here
  },
  // ... more class definitions
);

​
Card Styling

To customize card styles, edit the relevant card components or create your own card component with your desired styling: 
// components/ui/Card.tsx
const cardClasses = classNames(
  'bg-white dark:bg-gray-800 rounded-lg shadow-md overflow-hidden',
  'border border-gray-200 dark:border-gray-700',
  // Add your custom styles here
);

​
CSS Variables

PreLaunch uses CSS variables for consistent theming. You can override these variables in styles/globals.css: 
:root {
  --color-primary: #3b82f6;
  --color-secondary: #f59e0b;
  --color-background: #ffffff;
  --color-text: #1f2937;
  /* Add your custom variables here */
}

.dark {
  --color-primary: #60a5fa;
  --color-secondary: #fbbf24;
  --color-background: #111827;
  --color-text: #f9fafb;
  /* Dark mode overrides */
}

​
Adding Custom Components

You can create custom themed components by adding new files to the components/ui/ directory: 
// components/ui/CustomComponent.tsx
import classNames from 'classnames';

interface CustomComponentProps {
  variant?: 'default' | 'outline' | 'custom';
  // Other props
}

export const CustomComponent = ({ 
  variant = 'default',
  // Other props
}: CustomComponentProps) => {
  const classes = classNames(
    'base-class',
    {
      'default-variant-class': variant === 'default',
      'outline-variant-class': variant === 'outline',
      'custom-variant-class': variant === 'custom',
    }
  );
  
  return (
    <div className={classes}>
      {/* Component content */}
    </div>
  );
};
