Due to the lack of structure, HTML pages with good forms are hard to handle. You must analyze the title level to see how each part is divided. The sidebar, footer, header, navigation bar, main content area, and articles are all represented by common div elements. HTML 5 adds some new elements specifically used to identify these common structures:
· Section: this can be a chapter or section in the book. In fact, it can be anything with its own title in HTML 4.
· Header: the header displayed on the page. It is different from the head element.
· Footer: footer. It can display the signature in the email.
· Nav: A group of links pointing to other pages
· Article: an article in blogs, magazines, and Articles
Let's consider a typical blog homepage, with a header at the top, a footer at the bottom, several articles, a navigation area, and a sidebar. For details, see the typical blog page in Code 1.

Even with the correct indentation, these nested divs are still confusing. In HTML 5, you can replace these elements with semantic elements. For details, refer to the typical blog page written in HTML5 in Code 2.

Div is no longer needed. You no longer need to set the class attribute by yourself. The meaning of each part can be inferred from the standard element name. This is especially important for audio browsers, mobile browsers, and other non-standard browsers.
