Definition and function of HTML
<p> HTML is a markup language used to describe the structure and content of a web page. Its purpose is to enable the browser to understand and present the page layout and information you want. The power of HTML is its flexibility, you can use it to create simple text pages or build complex multimedia websites. <p> A simple HTML file looks like this: <!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>My First Webpage</title>
</head>
<body>
<h1 id="Welcome-to-My-Website">Welcome to My Website</h1>
<p>This is a paragraph of text.</p>
</body>
</html>How HTML works
<p> When you open an HTML file, the browser parses these tags and builds the DOM (Document Object Model) of the web page based on their content and properties. DOM is a tree structure, and each HTML element is a node in this tree. The browser converts the DOM into visible pages through the rendering engine.<p> Understanding how HTML works will not only help you write code better, but it will also make it easier to find solutions when you encounter problems. For example, understanding the nested relationships of tags can help you avoid common structural errors.Example of usage
Basic usage
<p> The basic usage of HTML is to define page elements through tags. For example,<h1> to <h6> are used to define titles, <p> are used for paragraphs, and <a> are used for links. Here is a basic HTML structure: <!DOCTYPE html>
<html lang="en">
<head>
<title>Basic HTML Structure</title>
</head>
<body>
<h1 id="Main-Heading">Main Heading</h1>
<p>This is a paragraph.</p>
<a href="https://www.example.com">Visit Example</a>
</body>
</html>Advanced Usage
<p> Advanced usage of HTML includes the use of semantic tags, form elements, and multimedia elements. Semantic tags such as<header> , <nav> , <article> , etc. can not only make your code more readable, but also improve the effectiveness of search engine optimization (SEO).<p> Here is an example using forms and multimedia elements: <!DOCTYPE html>
<html lang="en">
