What is the DOM (Document Object Model)?
Welcome to our first module! In this module, we will explore the fascinating world of DOM Manipulation!
Let’s start by understanding the DOM, which is the core of dynamic interactions on web pages.
The DOM, or Document Object Model, is like the structure of a house.
Imagine that a web page is like a house, and the DOM would be the skeleton of that house, which allows us to interact with each part of it.
Here’s the trick: the DOM represents the structure of the HTML document as a tree, where each element is a node.
Imagine a Christmas tree, where every ball and ornament is an HTML element. Each ball is linked to another, forming a hierarchy.
Let’s simplify it even further. Suppose we have a simple HTML document:
<!DOCTYPE html> <html> <head> <title>My Page</title> </head> <body> <h1>Hello World!</h1> <p>This is a paragraph.</p> </body> </html>
Now, this document is represented in the DOM as a tree, where <html>, <head>, <title>, <body>, <h1>, and <p> are all interconnected nodes.
DOM manipulation, which we will explore throughout this course, involves playing with these nodes, changing, adding or removing elements to create interactivity in our web pages.
Now that we have an overview of the DOM, let’s dive deeper into the basics of HTML and CSS in the next topic! Stay tuned to find out how these pieces fit together in this exciting web puzzle.
