What does the Body tag do in HTML: the most important element in HTML now?
The body element contains all the content of a web page. It must be placed inside the html parent element, next to the head element.
<html> <head> . . . </head> <body>The content of the page should be here</body> </html>
The most important… and simplest
The body element is the most important element in HTML. The content of the body element is what is actually shown to the user visiting your web page or viewing your document. The body tag should be placed after the html tag and after the head tag (if present).
<html>
<head>
<title>The body tag in HTML</title>
</head>
<body>

Styling with the body element
In previous versions of HTML (and in some proprietary browser markup schemes) a number of style attributes and events were available for the body tag. These are all obsolete in HTML5. Any style you wanted to apply with the body had to be placed in your CSS. And, in fact, the contents of the body tag are a great place to put all the CSS that’s used to display the document as a whole: such as fonts and typography, text colors, backgrounds, and other default styles.
Targeting the body tag
A common practice in content management systems is to place a list of content-specific CSS classes in the body element. This allows designers and JavaScript developers to target pages based on specific content attributes, such as category, tags, or content type.
These classes are added programmatically by various components and plugins, and provide an easy way for developers to target styling or functionality to the highlighted page content (if not used, they cause no problems).
