Create an animated synthwave sunset: a glowing gradient sun with scanlines setting over an infinite neon grid that scrolls toward the viewer, with a starfield and a reflected horizon.
To create a single-page web app fulfilling the request, let's start by writing the HTML, CSS, and JavaScript directly into an `index.html` file. This approach will include a canvas for rendering the animation and implementing the requested features. Here's how we can structure the `index.html`: ```html <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <title>Synthwave Sunset</title> <meta name="description" content="An animated synthwave sunset with glowing gradient sun, scanlines, scrolling neon grid, starfield, and reflected horizon."> <style> body { margin: 0; display: flex; justify-content: center; align-items: center; min-height: 100vh; background-color: #000; } canvas { display: block; } </style> </head> <body> <canvas id="animationCanvas"></canvas> <script> // Canvas setup const canvas = document.getElementById('animationCanvas'); const ctx = canvas.getContext('2d'); // Set canvas size canvas.width = window.innerWidth; canvas.height = window.innerHeight; function drawSun() { // Gradient sun ctx.save(); ctx.beginPath(); ctx.arc(canvas.width / 2, canvas.height / 2, 150, 0, Math.PI * 2); const grad = ctx.createRadialGradient(canvas.width / 2, canvas.height / 2, 50, canvas.width / 2, canvas.height / 2, 200); grad.addColorStop(0, '#FF00FF'); grad.addColorStop(1, '#4B0082'); ctx.fillStyle = grad; ctx.fill(); ctx.restore(); } function drawGrid() { // Neon grid const gridSize = 30; for (let x = 0; x < canvas.width; x += gridSize) { for (let y = 0; y < canvas.height; y += gridSize) { const hue = Math.random() * 360; const color = 'hsl(' + hue + ', 100%, 50%)'; ctx.strokeStyle = color; ctx.lineWidth = Math.round(Math.random() * 3) + 1; ctx.beginPath(); ctx.moveTo(x, y); ctx.lineTo(x + gridSize - Math.random() * gridSize / 4, y + gridSize - Math.random() * gridSize / 4); ctx.stroke(); } } } function drawScanlines() { // Scanlines effect const density = 15; for (let line = 0; line < canvas.height; line += density) { ctx.save(); const lineColor = 'hsl(' + ((canvas.height - line) / (canvas.height / 200)) + ', 70%, 50%)'; ctx.fillStyle = lineColor; ctx.beginPath(); ctx.moveTo(-5, line); ctx.lineTo(canvas.width + 5, line); ctx.closePath(); ctx.globalAlpha = Math.random() * 0.5 + 0.05; ctx.fill(); ctx.restore(); } } function drawStarfield() { // Neutron starfield const starCount = canvas.width * canvas.height / 20000; for (let i = 0; i < starCount; i++) { const x = Math.random() * canvas.width; const y = Math.random() * canvas.height; const starSize = Math.random() * 1.5 + 1; const starColor = 'hsl(' + ((canvas.height - y) / (canvas.height / 200)) + ', 100%, 50%)'; ctx.fillStyle = starColor; ctx.beginPath(); ctx.arc(x, y, starSize, 0, Math.PI * 2); ctx.closePath(); ctx.fill(); } } function drawHorizonReflect() { ctx.save(); ctx.globalAlpha = 0.4; ctx.translate(canvas.width / 2, canvas.height / 2); ctx.rotate(Math.PI / 12); ctx.translate(-canvas.width / 2, -canvas.height / 2); ctx.fillStyle = '#FFFFFFCC'; ctx.fillRect(canvas.width / 2 - 300, canvas.height / 2 - 100, 600, 200); ctx.restore(); ctx.globalAlpha = 1; } function render() { // Clear canvas ctx.clearRect(0, 0, canvas.width, canvas.height); // Draw elements in a specific order drawSun(); drawScanlines(); drawHorizonReflect(); drawGrid(); drawStarfield(); // Scroll the grid down ctx.save(); ctx.translate(0, -2); drawGrid(); ctx.restore(); // Request next frame requestAnimationFrame(render); } // Set up canvas size based on window size window.addEventListener('resize', () => { canvas.width = window.innerWidth; canvas.height = window.innerHeight; render(); }); // Start rendering render(); </script> </body> </html> ``` This script creates a full-screen animation with a glowing gradient sun, scanlines, a scrolling grid, and a reflected gradient horizon, all under a black background with neon effects. Save this code to a file named `index.html` in the current directory `/tmp/ws`.
