Tips: The browser will automatically Add blank lines before and after. h1 serves as the main heading (the most important), followed by h2 (the next most important), then h3, and so on. Tip: By default, HTML will automatically add an extra blank line before and after block-level elements, such as paragraphs and heading elements. 4a249f0d628e2318394fd9b75b4636b1 - 4e9ee319e0fa4abc21ff286eeb145ecc The align attribute is deprecated in HTML4/5.

HTML: 注释
可以将注释插入 HTML 代码中，这样可以提高其可读性，使代码更易被人理解。浏览器会忽略注释，也不会显示它们。
注释是这样写的：
cf2a8215cfeca7c74714a9990fb8e262
注释：命令行最后的两个正斜杠（//）是 JavaScript 注释符号。这确保了 JavaScript 不会执行 --> 标签。
除了在源文档中有非常明显的作用外，许多 Web 服务器也利用注释来实现文档服务端软件特有的特性。这些服务器可以扫描文档，从传统的 HTML/XHTML 注释中找到特定的字符序列，然后再根据嵌在注释中的命令采取相应的动作。这些动作可能是简单的包括其他文件中的文本（即所谓的服务器端包含，server-inside include），也可能是复杂地执行其他命令去动态生成文档的内容。
