What is the correct understanding of html

HTML, Hypertext Markup Language, is a markup language that is used to write web documents and implement the structure and content of web pages. HTML is an important part of web development, and its correct understanding helps developers better master web technology.

The original purpose of HTML is to display text (including images, links, etc.) to users, and to transfer and display text content and format between terminal devices and browsers. Therefore, to correctly understand HTML, you need to master it from the following three aspects:

1. The basic structure and syntax of HTML

The basic structure of HTML consists of tags, elements and attributes . Tags are names used to describe elements, elements are used to combine tags and attributes, and attributes are used to describe the characteristics of elements. The basic structure of an HTML document is as follows:

<title>Web Page Title</title>

< body>

<p>Web Page Content goes here.</p>

In the above code, the DOCTYPE statement in the first line selects the HTML version, and the following html tags are The root element of the document contains head and body elements. The head element contains the title element, and the body element contains other elements of the web page content.

2. Elements and Attributes of HTML

HTML elements are the basic building blocks in HTML. They define the structure of an HTML document. HTML provides many standard elements, such as text elements, image elements, link elements, etc. Element properties contain additional information such as size, color, links, etc. Some common HTML elements and their attributes are as follows:

• Text elements: p, h1-h6, li, ul, ol, etc.
• Image elements: img
• Link elements: a, href
• Form elements: form, input
• Multimedia elements: video, audio

3. Standards and specifications in HTML

The HTML standard is developed by the W3C (World Wide Web Consortium). W3C established HTML5 as the next generation baseline. HTML5 is an upgrade to existing HTML that supports more tags, attributes and APIs, making web development more flexible and sustainable.

In addition to HTML standards, there are also some related specifications, such as CSS (cascading style sheets), JavaScript, etc. These specifications are crucial to web development and play an important role in improving the readability, usability, and accessibility of websites.

In general, to correctly understand HTML requires understanding its basic structure and syntax, being familiar with common elements and attributes, and mastering relevant standards and specifications. HTML is the foundation of web development. It is closely related to the structure and content of web pages and will continue to play an important role.
