HTML5的文档结构相对简单，以下是一个基本的HTML5文档结构示例：
<!DOCTYPE html>
<html lang="zh-CN">
<head>
<meta charset="UTF-8">
<title>HTML5实训例题解析</title>
</head>
<body>
<!-- 页面内容 -->
</body>
</html>
二、HTML5实训技巧
2.1 实训环境搭建
在进行HTML5实训之前，首先需要搭建一个合适的实训环境。以下是一些建议：
- 开发工具：使用Sublime Text、Visual Studio Code等文本编辑器。
- 浏览器：Chrome、Firefox等主流浏览器。
