DOM vs HTML Explained 💻

Infographic explaining the difference between HTML and DOM in JavaScript, showing HTML as static source code and the DOM as a live browser representation manipulated by JavaScript.

 🌐 What is HTML?

HTML is the basic structure of a webpage. It is the code we write to create headings, paragraphs, buttons, and images.

HTML

<h1>Hello World</h1>

<p>This is HTML</p>

👉 HTML is a static file. It does not change on its own.


🌳 What is DOM?

DOM stands for Document Object Model. It is the browser’s representation of the HTML page.

👉 When a page loads, HTML becomes the DOM.

The DOM allows JavaScript to change the webpage dynamically.

⚡ Simple Difference

HTML = Written code (static)

DOM = Live version of HTML (dynamic)


🧑‍💻 Example

JavaScript

document.getElementById("title").innerText = "Hello DOM!";

👉 JavaScript changes the DOM, not the original HTML file.


🚀 Conclusion

HTML builds the page, and DOM allows JavaScript to interact with and change it.
