Editor to share with you a sample analysis of the main body of HTML, I believe that most people do not know much about it, so share this article for your reference, I hope you can learn a lot after reading this article, let's go to understand it!

HTML body

Tags are used to define the body content of a document and appear in pairs. In.。 The content between is the main content of the page, which can be text, image, audio, video, form, and other interactive content, which is what is really displayed in the browser and seen by the visitor.

Because HTML elements can be nested with each other, the ever-changing web pages are formed through the nesting of elements layer by layer. When an element contains another element, the outer element is called the parent element and the inner element is called the child element. Child elements can also contain child elements, and any element contained in the child element is a descendant of the outer parent element. Such as:

In the above code, the article element is the parent element of the H2, h3, and p elements, and the H2, h3, and p elements are the children (and descendants) of the article element. P element is the parent element of em and an elements. The em and an elements are children of the p element and are descendants of the article element (but not child elements). The article element is the ancestor of the em and an elements.

It is important to note that when an element contains other elements, each element must be properly nested, and the opening and closing tag pairs of these elements are not allowed to cross each other. Such as:

If you start p and then a, you have to end an and then p. In the above code, there is an intersection between the tag pairs of element an and element p, which is incorrect nesting.
