三、CSS代码

* {margin: 0;padding: 0;box-sizing: border-box;
}body {font-family: Arial, sans-serif;background-color: #0A0A2A;display: flex;justify-content: center;align-items: center;height: 100vh;overflow: hidden;position: relative;color: white;
}.center-container {display: flex;justify-content: center;align-items: center;z-index: 2;position: relative;
}.login-container {background: linear-gradient(145deg, #c8102e, #0a0a2a);padding: 40px;border-radius: 15px;box-shadow: 0 8px 30px rgba(0, 0, 0, 0.5);text-align: center;width: 300px;z-index: 2;
}.spiderman-logo img {width: 50px;height: 60px;margin-bottom: 5px;
}/* Form styles */
.login-form {display: flex;flex-direction: column;
}.input-group {margin-bottom: 20px;
}.input-group label {margin-bottom: 8px;font-size: 14px;float: left;
}.input-group input {width: 100%;padding: 10px;border: none;border-radius: 5px;background-color: #ffffff;color: black;font-size: 16px;
}button {padding: 10px 20px;border: none;background-color: #ff4c4c;color: white;font-size: 18px;border-radius: 5px;cursor: pointer;transition: background-color 0.3s ease;
}button:hover {background-color: #ff1c1c;
}#spider-web {position: absolute;top: 50%;left: 50%;transform: translate(-50%, -50%);z-index: 1;width: 100vw;height: 100vh;
}

四、JavaScript代码

const canvas = document.getElementById('spider-web');
const ctx = canvas.getContext('2d');canvas.width = window.innerWidth;
canvas.height = window.innerHeight;function drawWeb() {const centerX = canvas.width / 2;const centerY = canvas.height / 2;const radiusStep = 30;const radialStep = 10;const rings = 10;const lines = 12;for (let i = 1; i <= rings; i++) {ctx.beginPath();ctx.arc(centerX, centerY, radiusStep * i, 0, Math.PI * 2);ctx.strokeStyle = 'white';ctx.lineWidth = 1;ctx.stroke();}for (let i = 0; i < lines; i++) {const angle = (i / lines) * Math.PI * 2;const x = centerX + Math.cos(angle) * radiusStep * rings;const y = centerY + Math.sin(angle) * radiusStep * rings;ctx.beginPath();ctx.moveTo(centerX, centerY);ctx.lineTo(x, y);ctx.strokeStyle = 'white';ctx.lineWidth = 1;ctx.stroke();}for (let i = 1; i < rings; i++) {for (let j = 0; j < lines; j++) {const angle1 = (j / lines) * Math.PI * 2;const angle2 = ((j + 1) / lines) * Math.PI * 2;const x1 = centerX + Math.cos(angle1) * radiusStep * i;const y1 = centerY + Math.sin(angle1) * radiusStep * i;const x2 = centerX + Math.cos(angle2) * radiusStep * i;const y2 = centerY + Math.sin(angle2) * radiusStep * i;ctx.beginPath();ctx.moveTo(x1, y1);ctx.lineTo(x2, y2);ctx.strokeStyle = 'white';ctx.lineWidth = 1;ctx.stroke();}}
}drawWeb();
