Core Technologies

1. HTMX

• Used for dynamic updates and server interactions
• Enables partial page updates without full reloads
• Integrated with Django backend for seamless data exchange
• Used for form submissions and dynamic content loading

2. AlpineJS

• Handles client-side interactivity and state management
• Used for dropdowns, modals, and other interactive components
• Provides reactive data binding and event handling
• Key features used:
  • x-data for component state
  • x-show/x-if for conditional rendering
  • x-model for two-way data binding
  • x-on for event handling

3. Tailwind CSS

• Utility-first CSS framework for styling
• Custom configuration in tailwind.config.js
• Responsive design utilities
• Dark mode support with class-based implementation
• Custom color scheme with primary/secondary colors

Styling System

1. Base Styles

• Font: Poppins (400, 500, 600, 700 weights)
• Color Scheme:
  • Primary: Indigo (#4F46E5)
  • Secondary: Rose (#E11D48)
  • Gradients for interactive elements
  • Dark mode compatible color palette

2. Component Classes

• Button Variants:
  • .btn-primary: Gradient background with hover effects
  • .btn-secondary: Light/dark mode aware styling
  • Social login buttons with brand colors
• Form Elements:
  • .form-input: Styled input fields
  • .form-label: Consistent label styling
  • .form-error: Error message styling
• Cards:
  • .card: Base card styling with shadows
  • .auth-card: Special styling for authentication forms
• Status Badges:
  • .status-operating: Green success state
  • .status-closed: Red error state
  • .status-construction: Yellow warning state

3. Layout Components

• Responsive container system
• Grid system using Tailwind's grid utilities
• Flexbox-based navigation and content layouts
• Mobile-first responsive design

Interactive Components

1. Navigation

• Responsive header with mobile menu
• User dropdown menu with authentication states
• Theme toggle (light/dark mode)
• Mobile-optimized navigation drawer

2. Forms

• Form validation with error states
• CSRF protection integration
• File upload handling

3. Alerts System

• Timed auto-dismissing alerts
• Slide animations for entry/exit
• Context-aware styling (success, error, info, warning)
• Accessible notifications

4. Modal System

• HTMX-powered dynamic content loading
• Alpine.js state management
• Backdrop blur effects
• Keyboard navigation support
