Build a full modern website system for a Pet Adoption Center. Use clean HTML, Tailwind CSS, and JavaScript. The design must be modern, visually appealing, and aligned with the theme of pets, care, and adoption. Follow this structure: 1. Landing Page Create a beautiful, modern landing page. Use a friendly color palette (soft greens, blues, warm neutrals, or pet-themed colors). Include a hero section with a large banner image related to pets or adoption. Add a short tagline and description about the Pet Adoption Center. Add a “Get Started” button that leads users to the Login & Signup page. Ensure the layout is clean, responsive, and professional. 2. User Authentication Pages Create Login and Signup pages with a modern UI. Use a soft, minimalist card-style design. Include form validation (JavaScript allowed). After successful login, redirect the user to the User Dashboard. 3. User Dashboard Create a modern dashboard layout with 3 navigation tabs: View All Pets My Requests Updates / Announcements Use a responsive navbar or sidebar design. Each section must have clean card designs and well-organized content. Include sample pet cards (photo, name, type, breed). Include a section where users can view their adoption request status. Add an area for posting updates or announcements. 4. General Requirements Use consistent branding and color theme. Must be mobile-responsive. Include smooth animations or transitions for aesthetic feel. Use Tailwind CSS utility classes cleanly. Code should be well-structured and easy to understand.
