使用2个按钮在bootstrap中创建响应式导航栏

标签： html css twitter-bootstrap responsive-design

我想在bootstrap中创建一个有两个选项的导航栏。我希望按钮各占50％的屏幕尺寸。我已将div类设置为\\

这不是表明在所有这些屏幕尺寸上都会有12列吗？

现在，当屏幕较大（桌面全屏）时，两个按钮都可见，但是如果我选择移动视图，则按钮不可见。

我的代码如下：

<div class="col-md-12 col-xs-12 col-sm-12 col-lg-12">

为此更新了bootply：http://www.bootply.com/T0rLYTBJy2#

修改：This is the screenshot currently for large screens This is how it is coming for small screens

我正在尝试制作小屏幕＆amp;大屏幕看起来很像

以下是Bootly的图片，在大型vireport上显示链接而不是右侧的按钮。

以下两种方法可以做到这一点：一种是使用您当前的结构，但在所有视口中使移动导航“永久”。

第二种方法是使用占据整个导航栏的两个下拉按钮。

请参阅完整页面上的工作摘要。

示例1：仅限移动设备navbar的当前结构。
