? What You'll Create

Animated snowflakes falling gracefully.
A festive Christmas town glowing with holiday spirit.
Santa Claus flying across the night sky in his sleigh with realistic oscillating movement.
This project uses HTML, CSS, and JavaScript (Canvas API), making it perfect for beginners and experienced developers alike.

  1. Setting Up the HTML We'll start with a simple HTML structure:


    <meta charset="UTF-8">
    <title>Christmas Wonderland</title>
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <style>
        /* Add the CSS styles here */
    </style>


    <canvas>


<ol>
<li>Styling the Scene with CSS</li>
</ol>

<p>We use CSS to create the visual layers of the scene:</p>

<p>A gradient background to simulate the night sky.<br>
A city banner showcasing a cozy Christmas town.<br>
Layers for snow and Santa's animation.<br>
</p>

<pre class="brush:php;toolbar:false">body {
    margin: 0;
    overflow: hidden;
    background: linear-gradient(to bottom, #1e3b70, #29578a, #3a75b6, #a0d3e8);
    position: relative;
    height: 100vh;
    display: flex;
    flex-direction: column;
    align-items: center;
    justify-content: flex-start;
}

/* Canvas for the snow and Santa */
#skyCanvas {
    display: block;
    position: absolute;
    top: 0;
    left: 0;
    width: 100%;
    height: 100%;
    z-index: 2;
}

/* Section for the Christmas town */
#christmasScene {
    position: absolute;
    bottom: 0;
    width: 100%;
    height: 50%;
    z-index: 1;
    display: flex;
    align-items: flex-end;
    justify-content: center;
}

/* City banner */
#cityBanner {
    width: 100%;
    height: 100%;
    background: url('https://i.ibb.co/0p0Wzrk/DALL-E-2024-12-02-23-27.png') no-repeat center center;
    background-size: cover;
    background-position: bottom;
}
  1. Adding the Magic with JavaScript

Using the Canvas API, we'll bring our scene to life by:

Animating snowflakes with varying sizes, speeds, and movements.
Making Santa Claus fly across the sky with a smooth oscillating trajectory.

const canvas = document.getElementById('skyCanvas');
const ctx = canvas.getContext('2d');

let width, height;
let snowflakes = [];
let santa = {
    x: width,
    y: height * 0.1,
    width: 150,
    height: 80,
    image: new Image(),
    time: 0
};

// Load Santa's image
santa.image.src = 'https://i.ibb.co/rbHJDQB/DALL-E-2024-12-02-23-37-removebg-preview.png';

function init() {
    resize();
    createSnowflakes();
    animate();
}

function resize() {
    width = canvas.width = window.innerWidth;
    height = canvas.height = window.innerHeight;
    santa.x = width;
    santa.y = height * 0.1;
}

window.addEventListener('resize', resize);

function createSnowflakes() {
    let count = width / 8;
    snowflakes = [];
    for (let i = 0; i  height) {
        this.y = 0;
        this.x = Math.random() * width;
    }

    if (this.x > width) {
        this.x = 0;
    }
    if (this.x  {
        flake.update();
        flake.draw();
    });

    updateSanta();
    drawSanta();

    requestAnimationFrame(animate);
}

init();
