Agency — Marketing / Growth Landing
A full-page landing for a fictional growth marketing agency, Voltline. Bright purple-to-orange gradients on white drive an energetic, results-first mood across a sticky nav, a hero with an animated live revenue dashboard, four service cards, ROI-heavy case studies, an animated metrics band, a four-step funnel, client testimonials, and a validated book-a-call form. Vanilla JS handles the mobile menu, scroll reveals, count-up stats, and toast feedback.

</html>Marketing / Growth Landing
A complete one-page marketing site for Voltline, a fictional growth agency that “turns ad spend into predictable revenue.” The visual identity leans into a bright purple → pink → orange gradient on white, a punchy display typeface (Space Grotesk) paired with Plus Jakarta Sans, and generous spacing for an energetic, results-driven feel. The page flows top to bottom through a transparent sticky nav, a split hero with a tilted live-dashboard mockup, a social-proof logo strip, a four-card services grid, three ROI-forward case studies, a dark animated metrics band, a four-step process funnel, client testimonials, a high-contrast book-a-call section, and a multi-column footer.
The hero dashboard counts its revenue figure up from zero, the bar chart animates in, and the dark metrics band fires count-up stats the moment it scrolls into view. Every section reveals on scroll via IntersectionObserver, cards lift on hover, and the nav gains a solid backdrop once you scroll. Both the strategy-call form and the footer newsletter validate inline (highlighting bad fields) and confirm with a toast helper, while the mobile menu collapses into an animated hamburger.
Everything is vanilla — no frameworks, no build step — so the markup, styles, and one small script are easy to lift into any project and re-skin. A prefers-reduced-motion block disables the animations for users who opt out, and the layout reflows cleanly from wide desktop down to roughly 360px.
Illustrative UI only — fictional brand, not a real product.
