Customization Overview

Concept is built with customization in mind. This guide provides an overview of all the ways you can make the template your own.

Customization Approaches

1. Quick Customizations

• Change colors and fonts
• Modify spacing and sizes
• Toggle features on/off
• Adjust layouts

2. Intermediate Customizations

• Create custom themes
• Add new components
• Modify existing components
• Integrate new plugins

3. Advanced Customizations

• Restructure layouts
• Build custom applications
• Create new design systems
• Implement custom build processes

Customization Layers

SCSS Variables

The fastest way to customize Concept is through Sass variables:

// src/scss/_variables.scss
$primary: #5969ff;
$secondary: #6c757d;
$success: #28a745;
$font-family-base: 'Inter', sans-serif;
$border-radius: 0.375rem;

Component Overrides

Override specific components without modifying core files:

// src/scss/custom/_buttons.scss
.btn-primary {
  background: linear-gradient(45deg, $primary, lighten($primary, 10%));
  border: none;
  box-shadow: 0 4px 6px rgba($primary, 0.3);
}

Layout Modifications

Customize the overall layout structure:

// src/config/layout.js
export const layoutConfig = {
  sidebar: {
    width: '260px',
    collapsed: '70px',
    dark: true
  },
  header: {
    height: '70px',
    fixed: true
  }
};

Key Customization Files

Style Customization

• _variables.scss - Global Sass variables
• main.scss - Main stylesheet entry
• custom/ - Your custom styles directory

JavaScript Customization

• config/ - Configuration files
• js/custom/ - Custom JavaScript modules
• app.js - Main application logic

Layout Customization

• partials/layouts/ - Layout templates
• partials/components/ - Reusable components
• pages/ - Page templates

Customization Workflow

Step 1: Plan Your Changes

Before starting, identify:

• What needs to be changed
• Which files are affected
• Whether to override or modify
• Impact on other components

Step 2: Set Up Custom Files

Create a custom directory structure:

src/
├── scss/
│   └── custom/
│       ├── _variables.scss    # Your variables
│       ├── _components.scss   # Component overrides
│       └── _theme.scss        # Theme customizations
└── js/
    └── custom/
        ├── theme.js           # Theme switcher
        └── components.js      # Custom components

Step 3: Override Safely

Always override rather than modify core files:

// DO: Create custom/_buttons.scss
.btn-primary {
  // Your customizations
}

// DON'T: Modify components/_buttons.scss directly

Step 4: Test Thoroughly

• Test in development mode
• Build for production
• Check responsive behavior
• Verify cross-browser compatibility

Quick Start Examples

Change Primary Color

// src/scss/_variables.scss
$primary: #7c3aed; // Purple instead of blue

Change Font Family

// src/scss/_variables.scss
$font-family-base: 'Roboto', sans-serif;

// Add font import
@import url('https://fonts.googleapis.com/css2?family=Roboto:wght@300;400;500;700&display=swap');

Customize Sidebar Width

// src/scss/custom/_layout.scss
.sidebar {
  width: 280px; // Instead of 260px
  
  &.collapsed {
    width: 80px; // Instead of 70px
  }
}

Add Dark Mode

// src/js/custom/theme.js
export function initThemeSwitcher() {
  const toggle = document.getElementById('darkModeToggle');
  
  toggle?.addEventListener('click', () => {
    document.body.classList.toggle('dark-mode');
    localStorage.setItem('theme', 
      document.body.classList.contains('dark-mode') ? 'dark' : 'light'
    );
  });
}

Customization Best Practices

DO:

• ✅ Use variables for consistency
• ✅ Create custom files for overrides
• ✅ Document your customizations
• ✅ Test across browsers
• ✅ Keep customizations modular
• ✅ Use version control

DON'T:

• ❌ Modify core Bootstrap files
• ❌ Edit vendor libraries directly
• ❌ Use !important excessively
• ❌ Hardcode values
• ❌ Skip responsive testing
• ❌ Forget about accessibility

Common Customizations

1. Branding

• Logo replacement
• Color scheme
• Typography
• Favicon

2. Layout

• Sidebar behavior
• Header style
• Footer content
• Page width

3. Components

• Button styles
• Card designs
• Form elements
• Table layouts

4. Features

• Remove unused pages
• Add new functionality
• Integrate APIs
• Custom widgets

Advanced Customization

Creating a Theme System

// src/js/custom/theme-manager.js
class ThemeManager {
  constructor() {
    this.themes = {
      default: { primary: '#5969ff', secondary: '#6c757d' },
      dark: { primary: '#1a1a1a', secondary: '#2d2d2d' },
      corporate: { primary: '#003366', secondary: '#0066cc' }
    };
  }
  
  applyTheme(themeName) {
    const theme = this.themes[themeName];
    Object.entries(theme).forEach(([key, value]) => {
      document.documentElement.style.setProperty(`--${key}`, value);
    });
  }
}

Custom Build Process

// vite.config.custom.js
import { defineConfig } from 'vite';
import customPlugin from './plugins/custom';

export default defineConfig({
  plugins: [
    customPlugin({
      // Your custom options
    })
  ]
});

Troubleshooting Customizations

Styles Not Applying

1. Check import order in main.scss
2. Verify file paths
3. Clear browser cache
4. Check CSS specificity

JavaScript Errors

1. Check console for errors
2. Verify module imports
3. Ensure DOM is ready
4. Check for conflicts

Build Issues

1. Clear Vite cache
2. Check for syntax errors
3. Verify dependencies
4. Review build logs
