1、What is Website Source Code?
Website source code is the collection of instructions written in one or more programming languages that tell a web browser how to display a webpage. It consists of HTML, CSS, and JavaScript, among other languages, and is essential for the creation and maintenance of websites.
2、HTML (HyperText Markup Language)
HTML is the standard markup language for creating web pages and web applications. It defines the structure and content of a webpage, such as headings, paragraphs, images, links, and more. To understand HTML, you need to be familiar with the following:
- Elements: HTML elements are the building blocks of a webpage. They are defined by tags and can be nested within each other.
- Attributes: Attributes provide additional information about an element, such as its ID, class, or style.
- Doctype: The Document Type Declaration (DOCTYPE) specifies the version of HTML used on a webpage.
3、CSS (Cascading Style Sheets)
CSS is a stylesheet language that describes the presentation of a document written in HTML or XML. It is used to style the HTML elements, determining their colors, fonts, layout, and more. To master CSS, you should learn:
- Selectors: Selectors are used to target specific HTML elements and apply styles to them.

4、JavaScript
JavaScript is a programming language that enables interactive web pages. It is used to create dynamic content, manipulate the DOM (Document Object Model), and handle events such as clicks and key presses. To get started with JavaScript, you should:
- Variables: Variables store data that can be manipulated throughout your code.
- Functions: Functions are reusable blocks of code that perform specific tasks.

5、Other Technologies
In addition to HTML, CSS, and JavaScript, there are other technologies that play a crucial role in website source code:

In conclusion, understanding the essence of English website source code is essential for anyone involved in web development. By mastering HTML, CSS, JavaScript, and other related technologies, you can create stunning, functional, and accessible websites. This comprehensive guide has provided a solid foundation to help you embark on your journey to becoming a proficient web developer.
