Which page should the following nav-tabs be added to? <ul class="nav nav-tabs"> <li><a href="home.html">Home</a></li> <li class="active"><a href="profile.html">Profile</a></li> <li><a href="messages.html">Messages</a></li> </ul>

The nav-tabs provided are specifically designed to be added to the profile.html page because of the "active" class applied to the Profile tab. The "active" class indicates which tab is currently selected or viewed by the user. In this case, since the Profile page is the one that the user is currently on, highlighting it with the "active" class is appropriate to guide users visually. This helps them quickly identify their location within the navigation structure.

When users navigate to profile.html, they should see the Profile tab highlighted, while the other tabs (Home and Messages) would not be marked as active. This enhances the navigation experience by clearly indicating the current page to the user. Therefore, the inclusion of the nav-tabs in the profile.html file is logical for maintaining consistent navigation cues across the website.
