Introduction

This project demonstrates responsive web design principles using HTML5, CSS3, and Bootstrap 5.3. It features a mobile-first approach with adaptive layouts that respond to different screen sizes while maintaining visual consistency and usability.

  • Responsive image containers with border-radius
  • Dynamic column collapsing for mobile views

Bootstrap Integration

• Utilizes Bootstrap 5.3.2 via CDN for:
  • Responsive navbar component
  • Dropdown menus and form elements
  • Utility classes for spacing and alignment
• Custom styles extend Bootstrap components while maintaining consistency

Semantic Structure

• Clear content hierarchy with:
  • Header section with branding
  • Primary content area with thirds layout
