创建一个简单的刮刮乐奖券布局涉及HTML和CSS。以下是一个简单的示例，你可以根据需要进行修改或扩展：

HTML结构：

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>刮刮乐奖券</title>
    <link rel="stylesheet" href="styles.css">
</head>
<body>
    <div class="scratch-card">
        <div class="scratch-area">
            <p class="prize-hidden">一等奖</p>
            <canvas id="scratchCanvas" width="300" height="150"></canvas>
        </div>
        <div class="info">
            <p>刮开涂层，赢取大奖！</p>
        </div>
    </div>
    <script src="script.js"></script>
</body>
</html>

CSS样式 (styles.css)：

body {
    font-family: Arial, sans-serif;
    display: flex;
    justify-content: center;
    align-items: center;
    height: 100vh;
    background-color: #f5f5f5;
}

.scratch-card {
    width: 300px;
    border: 1px solid #ccc;
    border-radius: 10px;
    background-color: white;
    padding: 20px;
    box-shadow: 0 2px 10px rgba(0, 0, 0, 0.1);
    position: relative;
}

.scratch-area {
    position: relative;
    width: 100%;
    height: 150px;
    border: 2px solid #999;
    border-radius: 10px;
    background: silver; /* You can use an image for the scratchable layer */
    overflow: hidden;
}

.prize-hidden {
    position: absolute;
    top: 50%;
    left: 50%;
    transform: translate(-50%, -50%);
    font-size: 24px;
    color: white;
    text-align: center;
    width: 100%;
}

canvas {
    position: absolute;
    left: 0;
    top: 0;
}

.info {
    margin-top: 20px;
    text-align: center;
}

JavaScript交互 (script.js)：这部分是可选的，用于处理刮刮乐的交互。你可以使用HTML5的<canvas>元素和JavaScript来检测用户的刮擦动作。以下是一个简单的示例，仅用于演示：

const canvas = document.getElementById('scratchCanvas');
const ctx = canvas.getContext('2d');
let isDrawing = false;

function draw(e) {
    if (!isDrawing) return;
    ctx.lineWidth = 5;
    ctx.lineCap = 'round';
    ctx.strokeStyle = '#000';
    ctx.lineTo(e.clientX - canvas.offsetLeft, e.clientY - canvas.offsetTop);
    ctx.stroke();
    ctx.beginPath();
    ctx.moveTo(e.clientX - canvas.offsetLeft, e.clientY - canvas.offsetTop);
}

canvas.addEventListener('mousedown', (e) => {
    isDrawing = true;
    ctx.beginPath();
    ctx.moveTo(e.clientX - canvas.offsetLeft, e.clientY - canvas.offsetTop);
});

canvas.addEventListener('mousemove', draw);
canvas.addEventListener('mouseup', () => isDrawing = false);
canvas.addEventListener('mouseout', () => isDrawing = false);
