如何在HTML5，Css3和Vanilla js中实现三个图形的动态化？

要在HTML5、CSS3和Vanilla JS中实现三个图形的动态化，你可以按照以下步骤进行：

1. HTML结构

首先，创建一个基本的HTML结构，包含三个图形元素。

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>Dynamic Shapes</title>
    <link rel="stylesheet" href="styles.css">
</head>
<body>
    <div class="shape" id="shape1"></div>
    <div class="shape" id="shape2"></div>
    <div class="shape" id="shape3"></div>
    <script src="script.js"></script>
</body>
</html>

2. CSS样式

使用CSS3来定义图形的样式和动画效果。

/* styles.css */
body {
    display: flex;
    justify-content: center;
    align-items: center;
    height: 100vh;
    margin: 0;
    background-color: #f0f0f0;
}

.shape {
    width: 100px;
    height: 100px;
    margin: 10px;
    border-radius: 10px;
    background-color: #3498db;
    animation: moveShape 3s infinite alternate;
}

#shape1 {
    background-color: #e74c3c;
}

#shape2 {
    background-color: #2ecc71;
}

#shape3 {
    background-color: #f1c40f;
}

@keyframes moveShape {
    from {
        transform: translateY(0);
    }
    to {
        transform: translateY(20px);
    }
}

3. JavaScript动态化

使用Vanilla JS来动态改变图形的属性，例如颜色、大小和动画速度。

// script.js
document.addEventListener('DOMContentLoaded', () => {
    const shapes = document.querySelectorAll('.shape');

    shapes.forEach(shape => {
        shape.addEventListener('mouseover', () => {
            shape.style.backgroundColor = getRandomColor();
            shape.style.animationDuration = `${Math.random() * 3 + 1}s`;
        });

        shape.addEventListener('click', () => {
            const newSize = Math.floor(Math.random() * 50) + 50;
            shape.style.width = `${newSize}px`;
            shape.style.height = `${newSize}px`;
        });
    });

    function getRandomColor() {
        const letters = '0123456789ABCDEF';
        let color = '#';
        for (let i = 0; i < 6; i++) {
            color += letters[Math.floor(Math.random() * 16)];
        }
        return color;
    }
});
