Bootstrap provides a responsive navigation bar.

To add responsive features to the navigation bar, the content you want to collapse must be wrapped in <div> with classes. collapse and. navbar-collapse. The collapsed navigation bar is actually a button with class. navbar-toggle and two data-elements. The first is data-toggle, which is used to tell JavaScript what to do with the button, and the second is data-target, which indicates the element to switch. Create three <span> hamburger buttons with class. icon-bar. These will be switched to the elements in. nav-collapse <div>. To implement these functions, you must include the Bootstrap Collapse (Collapse) plug-in.
