Lustro Slideshow Template

Lustro Slideshow is a free, fully responsive nine-slide presentation template built with pure HTML, CSS, and JavaScript. No frameworks, no build tools, no dependencies. Designed around a calm, dark glassmorphic aesthetic with an indigo-to-pink gradient accent, it gives founders, agencies, and indie SaaS makers a polished foundation for product launches, internal demos, and investor decks. Every slide flows into the next with smooth cross-fade transitions, layered reveal animations, and considered typography that reads as confidently on a 4K display as it does on a phone.

The structure follows a real product launch narrative: a cinematic cover, a problem statement, a feature introduction with a tilted mock dashboard, a four-up capability grid, a transparent four-quarter roadmap, beta metrics with sparklines and a customer quote, a side-by-side comparison table with a "Recommended" badge, a cross-promo grid, and a closing call-to-action. Each section uses a unified design system of CSS custom properties, glass-card components, gradient text accents, and a shared font stack of Space Grotesk, DM Sans, and JetBrains Mono. Customizing one part updates the whole deck cleanly.

Navigation is built for both quick demos and long presentations. A popup table-of-contents menu lets viewers jump to any slide. Arrow keys, spacebar, and number shortcuts (1 to 9) work for keyboard-driven walk-throughs. Swipe gestures with vertical-scroll detection handle mobile. On phones the slides become genuinely scrollable when content overflows, the chrome unsticks itself into an in-flow footer to free up screen space, and a custom-styled gradient scrollbar replaces the browser's default. Drop the file into any folder and it just works.
