4 Clipboard API Examples
This collection showcases the modern Clipboard API, a secure and asynchronous replacement for the outdated document.execCommand('copy'). The examples focus on the promise-based methods navigator.clipboard.writeText() and readText(), demonstrating how to interact with the system clipboard in a non-blocking way. You’ll learn the core technical requirement of handling user permissions, a key security feature of this API. These demos provide clean, vanilla JavaScript solutions for implementing essential “copy to clipboard” functionality in any modern web application.

Glassmorphic HSL Color Palette Generator
This Glassmorphic HSL Color Palette Generator is a production-grade design tool that combines advanced color theory logic with a modern, translucent UI. Unlike simple randomizers, it uses HSL (Hue, Saturation, Lightness) mathematics to generate mathematically harmonious schemes (Analogous, Triadic, Split-Complementary) while simultaneously calculating WCAG accessibility ratios in real-time. (Requires: Tailwind CSS)

Neumorphic Color Palette with Sound
This interactive color palette collection utilizes JavaScript’s getComputedStyle and execCommand('copy') to extract RGB values from CSS-defined elements, convert them to HEX, and copy to clipboard. The neumorphic design is achieved through complex box-shadow properties that create extruded shapes, while click handlers trigger a full-screen toast notification (show class) that displays the copied value with dramatic typography and audio feedback.

Random Password Generator
This password generator combines advanced UI/UX: a custom range slider with dynamic filling (linear-gradient in JS) and pure CSS-styled checkboxes. The technical core utilizes window.crypto.getRandomValues for more cryptographically secure number generation.
