What is ‘<nav>’ Tag in HTML?

The navigation portion of a webpage is defined by the '<nav>' semantic HTML element. This component is made to have a variety of menus, bars, or links for navigating the website's numerous pages or parts. Its major goal is to give website visitors an organised and clear presentation of the navigation elements to make surfing easier.

By utilising this element, web designers can tell web browsers and search engines that the information encompassed by the "<nav>" tag signifies navigation. This could boost search engine optimisation (SEO) strategies and website accessibility. The ‘<nav>’ tag must be used correctly and should only be applied to legitimate navigational elements on the page.

In essence, the '<nav>' element makes it simpler for visitors to navigate and improves their overall user experience, making it simpler for them to discover the webpage's required information.

Properties of ‘<nav>’ Tag in HTML

  • The ‘<nav>’ tag's primary use is to specify a website's navigational structure. Links and other navigational tools that guide users to other web pages or website parts should be included.

  • The ‘<nav>’ tag gives the content it encloses a semantic meaning by indicating that the content comprises navigation links. This makes the page's structure easier to interpret for browsers, search engines, and assistive technologies.

  • Using the tag helps web designers make their websites more accessible because screen readers and other assistive devices can more quickly recognise the navigational elements, making the website more useful for those with impairments.

  • Depending on where the navigation is placed within the overall page layout, the element should be inserted at an appropriate place inside the or section of the HTML content.

  • Only real navigation elements should be marked up with the tag. It shouldn't be utilised for links that are unrelated to navigation, footers, or other sorts of content.

  • The tag itself lacks any distinctive style characteristics. Instead, to create the appropriate visual appearance, developers might utilise CSS to style the navigation components included within the section.

Drawbacks of ‘<nav>’ Tag in HTML

  • Some developers use it to contain non-navigational content, which can cause semantic errors and ambiguity for search engines and assistive technology. So, misuse of ‘<nav>’ tag is one of the major downsides.

  • The ‘<nav>’ tag can provide needless clutter in the HTML code, which makes it more difficult to manage and comprehend, even when used frequently throughout a webpage for minor navigational features.

  • Although the ‘<nav>’ tag can improve accessibility, incorrect use or inaccurate labelling of navigation links may still provide problems for users who rely on assistive technologies.

  • The ‘<nav>’ tag simply marks up navigation parts, that is why it has a narrow scope. It does not address responsive design issues or more complicated navigation structures, which may call for extra HTML and CSS techniques.

  • While using ‘<nav>’ can have some SEO benefits, if other essential SEO techniques are not used, overusing it may not have a substantial impact on a webpage's ranking in search engines.
