Question

我正在使用Bootstrap来构建菜单。当页面调整为小屏幕的大小时，我得到我的汉堡图标，它显示菜单中的所有项目。有没有办法隐藏该菜单中的一个项目？我不想让我的购物车出现在汉堡下面。我自己可以写一些jQuery代码来做到这一点，但我想知道Bootstrap是否已经有办法做到这一点？

            <button type="button" class="navbar-toggle btn-lg"> <span class="sr-only">Shopping Cart</span> <span class="glyphicon glyphicon-shopping-cart" aria-hidden="true"></span> </button>
            <a class="navbar-brand" href="#">Title</a> </div>

Answer 1

如果使用Bootstrap responsive utility classes hidden-*类，这很容易。在您的情况下，将hidden-xs添加到按钮。

<button type="button" class="navbar-toggle btn-lg hidden-xs">
