Day 05/21: Interactive Canvas & Logic with JavaScript 🖱️✨ Halfway through the first week of my 21-day challenge! Today, I stepped away from standard layouts to build an Interactive Mouse-Tracking Grid. Using dynamic DOM generation and event delegation, I created a "light-trail" effect that follows the cursor across the screen. Technical Highlights of Day 05: Dynamic Grid Generation: Used Math.floor and client dimensions to calculate the exact number of cells needed to fill any screen size perfectly. Proximity Logic: Implemented an index-based check to not only highlight the active cell but also apply a "fade" effect to the surrounding neighbors (Top, Bottom, Left, Right). Mathematical Constraints: Handled edge-case logic using the modulo operator (%) to ensure the light trail doesn't "wrap around" to the other side of the screen accidentally. Asynchronous Cleanup: Utilized setTimeout to manage the lifecycle of the active states, creating a smooth, trailing animation effect. Tech Stack: 🛠️ HTML5 | 🎨 CSS3 (Grid) | ⚡ JavaScript (Event Tracking) Building interactive experiences like this helps me understand how modern web animations and game-like UIs are structured!
