Hypertext Markup Language (HTML)5 introduces new elements into HTML for the first time. New structural elements include aside, figure, and section. New inline elements include time, meter, and progress. New inline elements include video and audio. New interactive elements are details, datagrid and command.
Structural elements
Due to the lack of structure, even good HTML pages are difficult to deal with. The level of the title must be analyzed to see how each part is divided. The sidebar, footer, header, navigation bar, main content area and articles are represented by common div elements. HTML 5 has added some new elements to identify these common structures: ection: This can be a chapter or section in the book, but it can actually be anything with its own title in HTML 4 header: header displayed on the page; different from head elements footer: footer; signatures in emails can be displayed nav: a set of links to other pages article: an article in blog, magazine, article compilation, etc.
Semantic block elements
In addition to structural elements, HTML 5 also adds some purely semantic block-level elements: aside: represents description, prompt, sidebar, quote, additional comment, etc., that is, content outside the main line of the narrative figure: a block-level image, which can also include description dialog: represents the dialogue between several people.
