2024-SANDHYA/Blood-Buddy — reverse-engineered prompt

Build me a clean and friendly website called Blood Buddy that helps people who need blood donation services. I want a home page that explains the purpose, a register page where someone can enter their name, contact details, blood group, and address, a donate page for people who want to help, and a help page for basic guidance. After a user adds their address, the site should make it feel easy to find nearby blood banks or donation help, even if it starts with a simple search or location based section rather than a full backend.

Please make it responsive, warm, and trustworthy, with red and white hospital style visuals, clear buttons, simple forms, a preloader, smooth scrolling, and a back to top button. Use only normal HTML, CSS, and JavaScript so it can run by opening the files in a browser. Keep the code organized and make the pages feel connected and ready for an open source blood donation project.
