Frontend Design – Sports Betting Exchange (Back/Lay) + Casino & Live Casino Platform

I’m ready to move forward with a pure-frontend build for my betting platform and I want the very first milestone to focus squarely on the Sports Betting Exchange. The back/lay interface is the showpiece, so that’s where I expect most of your creative energy: clear columns for back and lay odds, intuitive stake inputs, live price highlighting, and a detailed odds display that feels familiar to pro bettors yet remains uncluttered on mobile.

The overall aesthetic is a modern, dark casino theme. Every screen—from desktop widescreen down to the smallest phone—needs to respond fluidly without sacrificing legibility. I’ll supply brand colours and logo; you translate them into clean, component-based HTML, CSS and vanilla JavaScript. No frameworks are mandatory, but lightweight choices (e.g. Tailwind, Alpine) are fine if they keep the codebase tidy and dependency-free.

Once the exchange layout is locked, you’ll extend the same design language to the casino lobby, live-casino tables and market views, but the deliverable for this engagement is limited to frontend files only—no API hooks or backend logic.

Deliverables
• Fully responsive HTML/CSS/JS files for the Sports Betting Exchange, emphasising the back/lay section with a detailed odds and bet-slip presentation
• Embedded preview or hosted link demonstrating responsiveness across breakpoints
• Well-commented source code so future devs can wire in data feeds without design rewrites

I’ll test on Chrome, Safari, Firefox and a mix of iOS/Android devices; if the interface renders consistently and interaction feels snappy, we’re good to roll into the next modules.
