Bigspring is a light, friendly SaaS/startup marketing template (CRM/productivity-tool positioning) rebuilt pixel-faithfully as a 35-page, self-contained static clone with no framework and no build step. It reproduces the white base palette with mint/pale-teal section bands, a solid teal accent, hand-drawn "undraw"-style illustration art, Urbanist headings with Poppins body copy, a mega-menu nav, a Swiper testimonial/logo carousel, an FAQ accordion, and a real light/dark theme toggle (Tailwind .dark class based, with a boot script that honors prefers-color-scheme and persists the choice to localStorage). Generated with Claude Fable 5.
Home, About, Team, How It Works, Careers, Products index plus 4 product detail pages, Blog index (paginated) plus 8 blog post templates, Authors index plus 2 author detail pages, Case Studies index plus 6 client case-study detail pages (Google, Iconsquare, Jira, Slack, Spotify, Trello), Pricing (3-tier cards + FAQ accordion), standalone FAQ, Contact, Terms & Conditions, Privacy Policy, and a custom 404 page. All pages share the same header/footer chrome (partials/header.html, partials/footer.html) and design tokens.
This is plain HTML/CSS/vanilla JS — there is no package.json and no build step. Serve the folder with any static file server from the project root:
python3 -m http.serverThen open http://localhost:8000/ (or index.html directly) in a browser.
prompt.mdcontains the full build spec — color tokens, typography scale, motion/theme-toggle details, and the complete page-by-page layout breakdown used to build this clone.demo.mp4(withposter.jpgas its thumbnail) shows the site in motion, including the theme toggle and FAQ accordion.- Assets (vendored fonts, images, CSS, JS, and the Swiper library) live under
assets/; shared header/footer markup lives underpartials/.
Faithful clone of an existing design, recreated for study/learning. All credit for the original design goes to its creators.
