1、Understanding the Structure of an English Website Source Code:

Before diving into the details, it's essential to have a basic understanding of the structure of an English website source code.

HTML (Hypertext Markup Language) is the backbone of any website. It defines the structure and content of web pages. By analyzing the HTML code, you can identify the different elements and their hierarchy. For example, HTML elements such as<div>,<header>,<nav>,<section>,<article>, and<footer> are commonly used to structure web pages.

1、2 CSS:

CSS (Cascading Style Sheets) is used to style and layout web pages. It defines how HTML elements are presented visually. By examining the CSS code, you can learn about the colors, fonts, spacing, and positioning of elements. CSS selectors like.class,#id, andelement are used to target specific elements and apply styles.

1、3 JavaScript:

JavaScript is a programming language that adds interactivity and functionality to websites. It allows you to create dynamic content, handle user events, and interact with the server. Analyzing JavaScript code can help you understand how web pages respond to user actions, such as clicking buttons or submitting forms.

2、Decoding the HTML Source Code:

To decode the HTML source code of an English website, follow these steps:

2、1 Open the website in a web browser.

2、2 Right-click on the webpage and select "View Page Source" or pressCtrl + U (Windows) orCmd + U (Mac).

2、3 A new tab will open, displaying the HTML source code.

Now, let's dive into the details of decoding the HTML source code:

2、3.1 Elements and Attributes:

An HTML element consists of a tag, content, and attributes. For example,<div class="container">Content</div> is an HTML element with adiv tag, class attribute with a value of "container", and content inside the tags.

2、3.2 Element Nesting:

HTML elements can be nested within each other to create a hierarchical structure. For example, a<nav> element can contain<ul> and<li> elements to create a navigation menu.

2、3.3 Semantic Elements:

3、1 Open the website in a web browser.

3、2 Right-click on the webpage and select "Inspect" or pressCtrl + Shift + I (Windows) orCmd + Option + I (Mac).

3、3 A developer tools panel will open. Click on the "Sources" tab.

3、4 Right-click on the CSS file you want to inspect and select "Open in new tab."

Now, let's explore the details of decoding the CSS source code:

3、4.1 Selectors:

CSS selectors are used to target specific elements and apply styles. Common selectors include class selectors (.class), ID selectors (#id), and element selectors (element).

3、4.2 Properties and Values:

CSS properties define various aspects of an element's styling, such as color, font, spacing, and positioning. For example,color: red; sets the text color to red.
