Pagine Difficile
Real Estate — Urban Condo Tower Landing
A sleek, dark urban condo-tower landing page for the fictional Meridian Heights development. A glassy chrome-and-blue hero frames a gradient tower silhouette and a live floor-availability ticker, followed by a residences grid spanning studio to penthouse with mini floorplans and from-prices, an amenities strip of icon tiles, and an interactive floor selector that reveals remaining units per floor band with status badges. A validating register-interest form closes the page with toast feedback.

</html>Urban Condo Tower Landing
A full marketing landing page for Meridian Heights, a fictional 42-floor glass-and-chrome condo tower. The dark, modern hero pairs a gradient tower silhouette with a headline, key stats (from-price, residence count, floors, move-in), and a continuously scrolling availability ticker that reads live counts from each floor band. The aesthetic leans sleek and architectural — charcoal surfaces, glass-blue accents, chrome highlights, and tight uppercase typography in Inter.
Below the hero, a residences grid presents five layouts (Atrium Studio through the two-story Skyline Penthouse), each with a gradient “photo,” a generated SVG floorplan thumbnail, beds/baths/sq-ft specs, a price badge, and a status badge. An amenities strip of icon tiles covers the sky terrace, performance gym, 24/7 concierge, lap pool, residents’ lounge, and smart parking.
The interactive heart is the floor selector: a vertical rail of floor bands (Podium, Mid-Rise, High-Rise, The Crown) that — on click or arrow-key navigation — swaps the panel to list that band’s remaining units, each with a unit number, type, square footage, deterministic price (including a view premium for higher floors), and an available / reserved / sold status. A closing register-interest form validates name and email inline and confirms with a toast. All data and interactions run on vanilla JS with no dependencies.
Illustrative UI only — sample listings and data are fictional; not a real real-estate service.
