    How to make Glowing Neon Clock using HTML CSS & JavaScript

    Let’s create a Glowing Neon Clock using HTML, CSS, and JavaScript. This project will display a stylish, neon-lit clock that updates in real-time.

    We’ll use HTML to structure the clock, CSS to style it with a glowing neon effect, and JavaScript to handle the real-time updating of the clock.

    Let’s get started on building the Glowing Neon Clock. Whether you’re a beginner or an experienced developer, this project offers a fun and visually appealing way to practice your web development skills. Let’s make time shine with a neon glow!

    HTML :

    This HTML document sets up a basic webpage structure for a neon clock using external CSS and JavaScript. It includes a reference to the Google Fonts API for the “Nunito Sans” font and an external stylesheet for additional styling. Basic CSS rules are defined to reset margins, padding, and box-sizing, and to set a flexible layout for the body element to center its content. The body contains a wrapper div with an empty main element, and the JavaScript file `script.js` is linked at the end to add functionality.

    CSS :

    This CSS code styles and animates a 3D neon clock. The `html` and `body` elements set up the overall font size and background, respectively. The `.wrapper` and `main` elements define a 3D rotating and panning camera effect. The `.digits` class and its children style individual digits of the clock, using various `clip-path` shapes for segments of the digits. Animation keyframes (`camera-rotate`, `camera-pan`, `hue-rotate`) are defined for rotating, panning, and changing the hue of the clock, giving it a dynamic, neon-lit appearance. Shadows and additional effects enhance the 3D look.

    JavaScript:

    This JavaScript code creates and animates a digital clock with hours, minutes, and seconds displayed using 3D-style digits and colons, along with shadows for a neon effect. It initializes the digits and colons, updates the time every second using `requestAnimationFrame`, and adjusts the displayed time accordingly. Additionally, it applies specific styles for Safari browsers for compatibility. The clock elements are constructed dynamically using `document.createElement` and updated by setting their attributes to represent the current time.

    const bars = [
    	['end', 'top'],
    	['side', 'top', 'left'],
    	['side', 'top', 'right'],
