Mastering DOM with a Simple Example

When you open a website, you see text, buttons, images, and many interactive elements. But have you ever wondered how JavaScript interacts with all these elements?

That’s where the DOM (Document Object Model) comes into play.

DOM acts as a bridge between HTML, CSS, and JavaScript, allowing developers to create dynamic and interactive web pages.

What is DOM?

The Document Object Model (DOM) is a programming interface that represents an HTML document as a structured tree of objects.

In simple words:
DOM allows JavaScript to access, modify, and control HTML elements.

Structure of DOM
The DOM represents a webpage like a tree structure:

The entire document is the root

HTML elements are nodes

Each element can have child elements.

This structure is called a DOM Tree.

What Can You Do with DOM?

Using DOM, you can:

Change text content

Modify styles (color, size, etc.)

Add or remove elements

Handle events (click, input, etc.)

Create dynamic user experiences
