Sticky navigation is a navigation bar on the website that is frozen in its place. When the user scrolls up or down the site, the sticky navigation bar remains in the same place on the screen and does not move. This helps the user to easily access the other sections that are shown in the navigation bar.
Many websites are using the sticky navigation feature to improve the user experience and make navigation through the website easy for the user. The bar also encourages the user to explore the website more.
