Introduction
origin
The full English name of HTML is Hyper Text Markup Language. HTML is a markup language created by Tim Berners-Lee, the inventor of the Web, and his colleague Daniel W. Connolly in 1990. It is an application of the standard generalized markup language SGML.
Since 1990, HTML has been used as the information representation language of the World Wide Web, and files described using HTML need to be displayed through a web browser.
A hypermedia document on the World Wide Web (www) is called a page (foreign language: page).
The essence of web pages is hypertext markup language. By combining the use of other web technologies (such as scripting languages, public gateway interfaces, components, etc.), powerful web pages can be created.

[4] Scalability: The wide application of hypertext markup language has brought about requirements for enhanced functions and added identifiers. Hypertext markup language adopts the method of subclass elements to ensure system expansion. [4] Platform independence: Although personal computers are popular, there are many people using other machines such as MAC. Hypertext Markup Language can be used on a wide range of platforms, which is another reason for the popularity of the World Wide Web (WWW). [4] Versatility: In addition, HTML is the universal language of the Internet, a simple, universal, all-purpose markup language. It allows web page producers to create complex pages that combine text and images, and these pages can be viewed by anyone else on the Internet, regardless of the type of computer or browser used.
Edit mode
edit
Semi-WYSIWYG software, such as: FCK-Editer, E-webediter and other online web page editors; especially recommended: Sublime Text code editor (developed by Jon Skinner, Sublime Text2 is charged but can be tried indefinitely) WYSIWYG software, the most widely used editor, can create web pages without any knowledge of HTML, such as: AMAYA (produced by: World Wide Web Consortium); FRONTPAGE (produced by: Microsoft); Dreamweaver (produced by: Microsoft) Adobe). Microsoft Visual Studio (Produced by: Microsoft): Compared with semi-WYSIWYG software, WYSIWYG software has faster development speed, higher efficiency, and more intuitive performance.
