The origin of html:

The development of HTML (Hypertext Markup Language) can be traced back to the late 1980s and early 1990s, which was the early development stage of the Web. The following is the origin and development history of HTML.

  1. 1989: The founder of HTML is British physicist Tim Berners-Lee, an engineer at CERN (European Organization for Nuclear Research). Berners-Lee’s goal was to create a system for sharing scientific documents to promote scientific research collaboration. He developed a concept called “hypertext” for linking documents and information.

  2. 1990: Berners-Lee published the first HTML specification, which described the basic structure and tags of HTML. This is the prototype of HTML, defining basic elements such as titles, paragraphs, lists, and links.

  3. 1993: Berners-Lee publishes the first formal specification of HTML, HTML+ (HTML Plus), which introduces new elements such as images and tables.

  4. 1994: Marc Andreessen of MIT releases Mosaic, an early version of the web browser that first introduced a graphical user interface (GUI) that made the Web Become more user friendly. Mosaic’s success promoted the development of the Web.

  5. 1995: Netscape Communications Corporation releases Netscape Navigator, the first popular commercial Web browser. Netscape Navigator introduced new HTML tags and JavaScript scripting language, promoting the enrichment of Web content.

  6. 1996: The World Wide Web Consortium (W3C) is formed, led by Tim Berners-Lee, to develop Web standards. The W3C published the HTML 3.2 specification, which played a key role in standardizing HTML.

  7. 1997: W3C released the HTML 4.0 specification, introducing more style control and script support.

  8. 2000: W3C released the XHTML 1.0 specification, which is a combination of HTML and XML (Extensible Markup Language), emphasizing stricter markup rules.

  9. 2014: W3C released the HTML5 specification, which introduced many new features, such as multimedia elements, form controls, Canvas drawing, etc., to support more interactive and multimedia web applications.

  10. To date: HTML5 has become a mainstream web standard, supports the needs of modern web development, and is constantly developing and evolving. The W3C and other organizations continue to work to improve HTML standards.

The evolution of HTML has been a key driving force in the development of the Web, which has enabled the Web to evolve from its original text documents into a platform for multimedia, interactivity and complex applications. The continuous updating and development of HTML standards to adapt to the needs of new technologies and applications ensures that the Web continues to be the main platform for global information sharing and interaction.

What is HTML:

HTML (Hypertext Markup Language) is a markup language used to create and render web pages viewed in a web browser. It is the foundation of web development and is used to define the structure and content of web pages. HTML uses tags (also called elements) to identify and format text, images, links, tables, and other elements so that they are rendered as visual web pages in the browser.

Main features of HTML:

  1. Hypertext: HTML supports hypertext, which means you can create links within your document that allow users to easily navigate to other related pages or resources. These links are usually implemented through the tag.

  2. Structured: HTML documents are made up of nested HTML elements that are organized in a hierarchy to define the layout and content of the page. Usually, HTML documents include a header part () and a body part ().

  3. Tags and attributes: HTML elements consist of tags and attributes. Tags usually include a start tag and an end tag, such as

    is used to represent paragraphs,

    is used to end a paragraph. Attributes provide additional information to the element, such as , where src is the source attribute of the image.

  4. Text and multimedia: HTML supports text content such as headings, paragraphs, and lists, as well as multimedia elements such as images, audio, and video. These elements can be inserted and rendered using appropriate tags.

  5. Forms: HTML allows the creation of interactive forms where users can enter information. Form elements include text boxes, radio buttons, check boxes, drop-down lists, etc., which are usually wrapped in

    tags.

  6. Style and Layout: Although HTML defines the structure of a document, it does not directly handle the appearance of the page. Style and layout are usually implemented through CSS (Cascading Style Sheets), through which style attributes such as fonts, colors, and spacing can be defined.

  7. Interaction and scripting: HTML supports scripting languages such as JavaScript, allowing developers to add interactivity and dynamic features to web pages. Scripts are usually embedded into HTML documents through the
