HTML refers to Hypertext Markup Language (Hyper Text Markup Language).

    • HTML is not a programming language, but a Markup Language (Markup language)
    • Markup language is a set of tag tags (markup tag)
    • HTML uses tag tags to describe web pages

HTML tag tags are often referred to as HTML tags (html tag).

    • HTML tags are keywords surrounded by angle brackets , such as
    • HTML tags are usually paired up , such as <b> and </b>
    • The first label in the pair is the start tag , the second is the end tag
    • Start and end tags are also known as open tags and closed labels

HTML document = Web page

    • HTML Document Description Web page
    • HTML documents contain HTML tags and plain text
    • HTML documents are also called Web pages

The purpose of a Web browser is to read HTML documents and display them as Web pages. Instead of displaying HTML tags, the browser uses tags to interpret the contents of the page:

Example explanation
 
 
    
  
  
       
   
    • Text description page between  
      • 
   
    • The text between <body> and </body> is visible in the page content
      •  
   
    • The text between  
      • 
   
    • Text between <p> and </p> is displayed as a paragraph
      •  
  
    
 
 
Another example:
<! DOCTYPE html>
Markup Language (Markup Language) uses a set of "tags" to "annotate" (annotate) plain text. For HTML, this set of tags is a variety of tags (tag), such as 

 
  
    
  
   
       
    
    • <! DOCTYPE html>
      •  
   
    
 
  
Called the document type declaration (documents type Declaration). It declares that the type of this document is HTML5. There are multiple versions of HTML, different versions of the supported tags and their attributes, and the syntax is subtle, HTML5 is a widely used version. In addition, if an HTML text does not have a document type declaration, the browser enables Quirk mode to interpret the document. This model is primarily designed to be compatible with older, non-compliant HTML documents. You should always add a document type declaration to the newly written HTML document.
