Bootstrap implements responsive navigation bar effect_javascript skills-JS Tutorial-php.cn

In order to add responsive features to the navbar, the content you want to collapse must be wrapped in a

with classes .collapse, .navbar-collapse. The collapsed navigation bar is actually a button with class .navbar-toggle and two data- elements. The first is data-toggle, which tells JavaScript what to do with the button, and the second is data-target, which indicates which element to switch to. Three with class .icon-bar create so-called hamburger buttons. These will switch to elements in .nav-collapse

. In order to achieve these features, you must include the Bootstrap Collapse plugin.
