Modern CSS & JS Showcase

A proof-of-concept page generated by Gemini 1.5 Pro. This single file demonstrates responsive layouts, animations, and interactivity to showcase modern web development techniques.

See The Features

Responsive CSS Grid

This layout uses `grid-template-columns: repeat(auto-fit, minmax(300px, 1fr))` to create a fully responsive grid that wraps automatically without any media queries.

Glassmorphism UI

A popular modern design trend. Achieved with a semi-transparent background, a `backdrop-filter: blur()`, and a subtle border to create a "frosted glass" effect.

CSS Animations

The background features a slow, shifting gradient powered by `@keyframes`. Hover effects use `transition` for smooth transformations. The title has a subtle text glow.

JS Interactivity

This page uses JavaScript for the scroll progress bar at the top and for the fade-in-on-scroll effect for these cards, powered by the efficient `IntersectionObserver` API.

CSS Custom Properties

All colors, shadows, and fonts are defined as variables in `:root`. This makes the design system consistent, maintainable, and easy to update or theme.

Modern & Accessible

Built with semantic HTML5 tags (`main`, `section`, `footer`), responsive units like `clamp()` for fluid typography, and `prefers-reduced-motion` considerations (implicitly via transitions).
