HTML-Navigationselement

The navigation element

tag inside an HTML document is used to specify a block of navigation links being enclosed, either within the same document or any other documents. Examples showcasing navigation blocks are indexes, tables of contents, menus, etc. An HTML document could contain as many as required

tags, such as site navigation, intra-page navigation, etc. The

tag is also used for declaring the navigational sections within HTML documents. Most websites typically prefer having sections dedicated to navigational links, which allow users to navigate on the site. These links can be placed within a nav tag. In this topic, we are going to learn about Html Nav Element.

Note:

• All the links mentioned in the HTML document are not placed inside the
  element; it only includes major navigation blocks. It can also be used for defining links in the footer of the website, but the

  tag is usually used in such cases.
• The
  HTML element is not allowed to be nested in the

  element.
• Both Start and End tag are required for Nav tag in HTML5 i.e.

Use of

tag

The

tag is chartered for primary navigation areas, such as the main menu across the top of a page or section. A document can have many

elements, i.e. one for site navigation, one for intra page navigation, etc. The links inside

tag can be codes within a ul list or can be simply coded as separate links without a ul element. This tag helps make it much easier to create things such as a navigation menu, the neat horizontal menu of text links, or a help screen reading software to identify primary navigation areas in the document correctly.
