1、Introduction to Website Source Code
The source code of a website is a collection of instructions written in a programming language, which browsers use to interpret and display the website. These instructions are typically found in HTML (Hypertext Markup Language), CSS (Cascading Style Sheets), and JavaScript. While HTML provides the structure, CSS handles the visual appearance, and JavaScript enables interactive elements.
1、1 HTML
HTML is the backbone of any website. It uses tags to define the structure and content of web pages. Common HTML tags include headings, paragraphs, lists, images, links, and forms. An example of a simple HTML code is as follows:
<!DOCTYPE html> <html> <head> <title>My Website</title> </head> <body> <h1>Welcome to My Website</h1> <p>This is an example of an HTML page.</p> <img src="image.jpg" alt="Example Image"> <a href="https://www.example.com">Visit Example</a> </body> </html>
1、2 CSS
CSS is responsible for the visual presentation of a website. It defines the layout, colors, fonts, and other stylistic elements. CSS can be applied to HTML elements using various selectors, such as class, id, and element selectors. An example of a CSS code snippet is as follows:
body {
font-family: Arial, sans-serif;
background-color: #f0f0f0;
}
h1 {
color: #333;
}
p {
color: #666;
line-height: 1.6;
}1、3 JavaScript
JavaScript is a scripting language that enables interactive elements on a website. It can manipulate HTML and CSS, handle events, and communicate with servers. An example of a JavaScript code snippet is as follows:
function myFunction() {
document.getElementById("myElement").innerHTML = "Hello, World!";
}
window.onload = function() {
myFunction();
};2、The Structure of an English Website Source Code
An English website source code typically follows a structured format, which includes the following components:
2、1 Doctype Declaration
The doctype declaration specifies the version of HTML used in the document. For example,<!DOCTYPE html> indicates that the document is written in HTML5.
2、2 HTML Elements

HTML elements make up the structure of a web page. These elements are organized into a hierarchical tree, with the<html> element as the root. The following are some common HTML elements:
<head>: Contains metadata about the document, such as the title and character encoding.
<body>: Contains the visible content of the web page.
<header>: Represents introductory content or a set of navigational links.
<nav>: Defines a section of navigation links.
<main>: Represents the main content of the document.
<article>: Defines a self-contained composition in a document.
<section>: Defines a thematic grouping of content.
<aside>: Represents content aside from the content it is placed in.
<footer>: Defines a footer for a document or section.
2、3 CSS Stylesheets
CSS stylesheets are linked to the HTML document using the<link> tag in the<head> section. These stylesheets contain CSS rules that define the appearance of HTML elements.
2、4 JavaScript Files
