How to View a Website’s Source Code Easily

Learn step-by-step how to view and explore the HTML, CSS, and JavaScript behind any website—on desktop and mobile—optimized for SEO and ranking on Google.

Introduction

Understanding the source code of a website can be an invaluable tool, whether you're a beginner learning how websites work or a professional optimizing for SEO and performance. Source code reveals the HTML structure, CSS styles, and JavaScript logic behind the visual interface of any website. By learning how to view and interpret source code effectively, you can gain insights into web design, functionality, and strategy.

What Exactly Is "Source Code"?

Source code is the raw set of instructions and assets that make up a webpage. When you load a website, your browser requests HTML, CSS, JavaScript, images, and other resources from a server. These components are then rendered into the user interface you see.

Components of Source Code:

  • HTML (HyperText Markup Language): Defines the structure and content.

  • CSS (Cascading Style Sheets): Controls the appearance and layout.

  • JavaScript: Adds interactivity and dynamic behavior.

  • Meta Tags & Structured Data: Crucial for SEO and social media previews.

Knowing how these elements work together can help you optimize performance, troubleshoot bugs, and analyze competitors.

Viewing Source Code on Desktop Devices

Using “View Page Source” Option

Nearly every web browser allows you to view the static HTML of a webpage using a simple built-in option:

Steps:

  1. Right-click anywhere on the webpage (avoid clicking on images or interactive areas).

  2. Select "View Page Source" from the context menu.

  3. Alternatively, press Ctrl+U (Windows/Linux) or Cmd+Option+U (macOS).

What You'll See:

  • HTML document from the server (not live DOM updates).

  • Meta tags, links to CSS/JS, inline scripts.

  • Text and structure as sent to the browser.

Using Developer Tools (Inspect Element)

Developer tools provide a far more interactive and detailed view of a website's front-end code.

How to Open:

  • Right-click on any page element → Choose "Inspect".

  • Or press Ctrl+Shift+I (Windows/Linux) or Cmd+Option+I (macOS).

Important Panels:

  • Elements: Live DOM structure with real-time updates.

  • Styles: Shows applied CSS rules and overrides.

  • Console: Logs errors, warnings, and JavaScript output.

  • Network: See resources loading and check performance.

  • Sources: View and debug JavaScript and CSS files.

Accessing CSS and JS Files

Many websites use external files. To view them:

  1. Open DevTools → Click "Sources" tab.

  2. Browse folders on the left (e.g., /assets, /js, /css).

  3. Click any file to open and read its content.

Viewing Source Code on Mobile Devices

On Android (Using Chrome)

You can use a URL prefix to view source code:

  • Open Chrome.

  • Type view-source: before the URL (e.g., view-source:https://example.com).

  • Press Enter.

Limitations: Hard to read due to small screen, no syntax highlighting.

On iOS (Using Safari)

Apple restricts source viewing directly on iPhones. However, you can:

  1. Connect your iPhone to a Mac via USB.

  2. Enable Developer Mode in Safari Preferences.

  3. Open the target site on Safari iOS.

  4. On your Mac, click "Develop" menu → Select your iPhone → Inspect the page.

Alternatively, use third-party apps that display source code, like "View Source" or "HTML Viewer" from the App Store.

Debugging JavaScript

  • Use the Console for real-time output.

  • Use Breakpoints to pause and inspect code behavior.

Prettifying Minified Code
