AGNCI — Webflow HTML Website Template
A professional agency-style website rebuilt from scratch using pure HTML5, CSS3, and JavaScript — inspired by the AGNCI Webflow template and fully reconstructed without exporting any Webflow code.
AGNCI is a hands-on learning project born from a desire to go deeper than tutorials. Instead of exporting the Webflow template, the VisBug browser extension was used to inspect every element — spacing, typography, layout, color — and the entire site was rebuilt line by line from scratch.
The result is a clean, lightweight, production-ready agency template with full responsive support across all major breakpoints, dark mode, accessibility features, and a mobile hamburger menu — built with zero dependencies and no build process required.
