Artillery Gorilla Canvas Retro Game is a plain JavaScript clone of the MS-DOS classic, QBasic Gorillas. Two gorillas on city rooftops take turns throwing explosive bananas, with calculations factoring in gravity, adjustable angles, and wind speed shown via an animated SVG windmill. It features single-player AI simulation, local two-player, dark/light modes, and destructible building hitboxes.

Direction-Aware CSS Box Shadow provides a reusable JavaScript class (DirectionAwareShadow) that calculates the mouse’s offsetX and offsetY relative to an element’s center. It then dynamically updates the element’s inline box-shadow property to cast a shadow in the opposite (or same) direction of the cursor. The class is highly configurable, allowing developers to easily adjust blur, spread, color, and offset intensity.

Interactive CSS Tear Strip Animation simulates the satisfying physical action of tearing open a cardboard package. It cleverly uses an invisible <input type="range"> linked to the CSS Scroll-Driven Animations API (animation-timeline: --thumb). As the user drags the slider, CSS variables dynamically update clip-path, box-shadow, and transform properties to reveal the content beneath while curling the torn strip. A JavaScript fallback ensures compatibility for browsers without native scroll-timeline support.

JavaScript Object Smartwatch Concept turns a standard digital clock into a clever developer joke. The UI mimics an Apple Watch using pure CSS (box-shadow for the bezel, linear-gradient for the strap). Inside, JavaScript’s requestAnimationFrame continuously updates a formatted string, rendering the current time and date as a syntax-highlighted JS object. A fun, lightweight snippet for developer portfolios.

“Morphing Stripe-Style Dropdown Navigation” replicates the famous Stripe header effect. A single background element dynamically resizes and moves behind the active content. JavaScript calculates dimensions using getBoundingClientRect() and updates CSS properties to animate the panel. This approach keeps the DOM clean and ensures smooth transitions between menu sections.

Pure CSS Trigonometric Flight Range Slider uses CSS math functions like sin() and clamp() to dynamically scale a custom airplane thumb and cast realistic altitude shadows based on the input’s current percentage. It features a responsive container query that swaps the plane for a helicopter on narrow screens, and includes dedicated high-contrast mode styles for robust accessibility.

Rollback Ball 3D Toggle Switch is a highly tactile, skeuomorphic switch concept. When clicked, a textured 3D ball realistically rolls across the track, cast-shadows shifting in unison. An ES6 JavaScript class dynamically reads the CSS animation duration, disables the input during the roll, and automatically resets the toggle state once the animation completes. A stellar example of interactive micro-design.

Scroll-Driven Crawling Border Frame draws a colorful frame around the viewport as the user scrolls. Utilizing native CSS Scroll-Driven Animations (animation-timeline: scroll()) and sequence keyframes, the borders of two fixed elements expand in height and width. The styling utilizes modern oklch() color math for a vibrant gradient. Clean, pure CSS decoration with no JS overhead.

Single Div Vintage TV CSS Illustration is a masterclass in CSS gradient art. Using only one div and its ::before/::after pseudo-elements, it renders a retro television set. The body, screen, antenna, and speaker grill are meticulously drawn using layered linear-gradient, radial-gradient, and repeating-linear-gradient. The mask-image property is cleverly used to carve out the control knobs. A brilliant example of pushing CSS drawing to its limits.

VisionOS Hexagonal App Grid Ripple recreates the spatial UI aesthetic of Apple VisionOS. It uses complex clip-path polygons to form the hexagons and backdrop-filter for the glassmorphism effect. The standout feature is the JavaScript-calculated ripple animation: on click, JS measures the distance from the target to every other hexagon, updating a CSS custom property (--ripple-factor) to stagger the CSS @keyframes delay radially.
