Tabs are one of the most frequently used components of mobile UIs, and for good reason.

They allow users to quickly move between a small number of equally important panes and bring a real-world element to the web and mobile applications. When implemented correctly, tabs can be an excellent user interface control element that can greatly improve usability.

They are considered to be very intuitive and easy to use. Well-designed tabs clearly indicate the user’s current location using a different visual appearance that sets active tabs apart from the others.

If you need a practical example, look no further than your desktop browser.
