The <body> HTML element represents the main content area of an HTML document. It encapsulates all the visible content that users see when they visit a webpage. The <body> element should be placed directly inside the <html> element.

Here’s an example of the basic structure of an HTML document with the <body> element:

<!DOCTYPE html>
    <title>My Webpage</title>
    <h1>Welcome to My Webpage</h1>
    <p>This is the main content of the webpage.</p>

In this example, the <body> element contains a heading (<h1>) and a paragraph (<p>), representing the main content of the webpage.

The <body> element can contain various types of content, such as text, headings, paragraphs, images, links, lists, forms, and more. It serves as a container for all the visible elements and provides the structure for the webpage’s content.

You can apply CSS styles and JavaScript functionality to the <body> element to control the appearance and behavior of the content within it.

It’s important to note that there should be only one <body> element per HTML document, and it should contain all the visible content of the webpage.

In summary, the <body> element is the central container for the visible content of an HTML document. It defines the main area where you display text, images, and other elements that make up your webpage.
