HTML DOM manipulation with JavaScript

HTML DOM (Document Object Model) is a standard interface for accessing HTML documents. JavaScript can be used to manipulate HTML DOM, which means that you can dynamically change the content and appearance of HTML elements on a web page. Here’s an overview of how to manipulate HTML DOM with JavaScript:

• Accessing HTML Elements

To manipulate HTML elements with JavaScript, you first need to access them. You can access HTML elements by their tag name, ID, class name, or CSS selector using various methods provided by the DOM API.

• Changing Element Content

Once you have accessed an HTML element, you can change its content by modifying its innerHTML property.

• Changing Element Attributes

You can also change the attributes of an HTML element using JavaScript. To do this, you can access an element’s attributes using the getAttribute() method and set them using the setAttribute() method.

• Adding and Removing Elements

You can add new HTML elements to a web page using JavaScript by creating new elements using the createElement() method and adding them to the DOM using the appendChild() method. You can also remove elements using the removeChild() method.

• Responding to Events

JavaScript can also be used to respond to user events such as clicks, key presses, and form submissions. To do this, you can attach event listeners to HTML elements using the addEventListener() method.
