What is it?

HTML (HyperText Markup Language) is the standard markup language for creating web pages and web applications. Created by Tim Berners-Lee at CERN in 1991, HTML defines the structure and content of a web page using a system of tags and attributes enclosed in angle brackets. Every web page you visit is built on an HTML document that your browser interprets and renders as a visual page.

HTML documents are plain text files with the.html or.htm extension. They contain elements like headings, paragraphs, links, images, tables, forms, and embedded media, defined by start and end tags. Modern HTML5 (standardized in 2014) added native support for audio, video, canvas drawing, semantic structural elements, and offline capabilities. HTML works together with CSS for styling and JavaScript for interactivity to form the three foundational technologies of the web.

Pros & Cons

Advantages

通用浏览器支持

Every web browser on every device can render HTML without any plugins or software.

人类可读

Plain text format that can be read and edited in any text editor.

超链接

The HyperText part of HTML enables the linking between pages that is fundamental to the web.

开放标准

Developed as an open, royalty-free standard by W3C and WHATWG with no licensing requirements.

Disadvantages

仅结构(无 CSS)

HTML alone produces unstyled, visually basic pages - presentational design requires CSS.

无数据逻辑

HTML is a markup language, not a programming language. Business logic and interactivity require JavaScript or server-side languages.

浏览器渲染不一致

Older or non-standard browsers may render HTML differently, requiring careful cross-browser testing.

冗长的语法

HTML requires opening and closing tags for most elements, making documents verbose compared to Markdown or plain text.

When to Use It

Here are the most common situations where HTML is the right choice:

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.
