HTML/CSS/JS Auth Pages

I have a small React project that contains a marketing landing page and the full login lifecycle (sign-in, sign-up, e-mail/user verification) plus a simple contact screen. I now need every one of those pages rebuilt from the ground up in plain HTML, CSS and vanilla JavaScript—no React, no Bootstrap, no external UI frameworks.

The new landing page must follow a modern, sleek aesthetic; I will share Figma screenshots and reference sites so you can match spacing, colour palette and typography. Subtle hover states on buttons and links are required, and a lightweight, touch-friendly carousel/slider will showcase three hero banners. Please keep the code modular so I can drop new slides in later.

Each form (login, registration, contact, verify e-mail/user) must:

• look identical to the React versions I provide,
• validate inputs client-side with clean ES6 JavaScript,
• trigger the same POST/GET endpoints (I will supply the URLs), and
• display inline error messages exactly where they appear today.

The layout needs to be fully responsive, using Flexbox or CSS Grid, and should perform consistently across the latest Chrome, Firefox, Safari and Edge.

Deliverables
• landing.html with linked carousel script and style sheet
• login.html, register.html, verify.html, contact.html and their shared CSS/JS modules
• all assets (images, SVGs, web fonts) organised in logical folders
• a brief README explaining file structure and where to wire back-end endpoints.
Highly Performant landing page.

I will test by dropping the build into an empty Apache folder; if every page renders perfectly, forms fire off to my API, and Lighthouse shows no critical issues, the work is complete.
