它是什么?
HTML (HyperText Markup Language) 是用于创建网页和网络应用的标准标记语言。由 Tim Berners-Lee 在 1991 年在 CERN 创建，HTML 使用一套由尖括号括起的标签和属性系统来定义网页的结构和内容。你访问的每个网页都基于一个 HTML 文档，你的浏览器会解析并将其呈现为可视页面。
HTML 文档是扩展名为 .html 或 .htm 的纯文本文件。它们包含由开始标签和结束标签定义的标题、段落、链接、图像、表格、表单和嵌入媒体等元素。在 2014 年标准化的现代 HTML5 为音频、视频、canvas 绘制、语义结构元素和离线功能提供了原生支持。HTML 与 CSS 配合用于样式设置，与 JavaScript 配合用于交互性，共同构成了网络的三大基础技术。

优缺点
Advantages
Every web browser on every device can render HTML without any plugins or software.
Plain text format that can be read and edited in any text editor.
The HyperText part of HTML enables the linking between pages that is fundamental to the web.
Developed as an open, royalty-free standard by W3C and WHATWG with no licensing requirements.
Disadvantages
HTML alone produces unstyled, visually basic pages - presentational design requires CSS.
HTML is a markup language, not a programming language. Business logic and interactivity require JavaScript or server-side languages.
Older or non-standard browsers may render HTML differently, requiring careful cross-browser testing.
HTML requires opening and closing tags for most elements, making documents verbose compared to Markdown or plain text.
何时使用
以下是 HTML 最适合的最常见情况：
网页
Every page on the World Wide Web is an HTML document. HTML is the universal format for all web content.
Web 应用接口
HTML5 forms the structural layer of web applications including single-page apps and progressive web apps.
电子邮件模板
HTML is used for formatted emails in email clients that support rich text.
文档和电子书
HTML is used as the source format for many ebook standards including EPUB, which packages HTML pages in a zip archive.
How to open a HTML file
When it comes to working with HTML files, software can be categorized into professional editors, free/open-source tools, web browsers, and built-in applications. Professional editors like Adobe Dreamweaver are suited for developers needing advanced features, while free/open-source options like Visual Studio Code cater to those on a budget. Browsers like Google Chrome and Firefox provide basic viewing capabilities, and built-in tools like Notepad offer minimal editing for casual users.
Key decision factors for choosing HTML software include feature fidelity, the distinction between editing and viewing, cost models, and platform compatibility. Users should consider whether they need robust editing features or simple viewing capabilities, as well as whether they require cross-platform support. Export needs can also influence the choice, particularly if converting HTML to other formats is necessary for their workflow.
