为什么我的下拉按钮点击后，右侧的导航栏就消失了，而且，展开后的导航为什么宽度没有占满整个屏幕
1回答

1. 因为点击导航时 ,下拉菜单把右侧图标导航给挤下来了 . 如下 :
可以把右侧整体的代码结构调整到下拉导航的上面 ,如下 :
2. 导航宽度没有沾满屏幕是因为bootstrap中 ,div.container有默认的填充影响 ,如下
可以自己定义样式去覆盖默认样式 优化一下哦 ,如下 :
因为bootstrap的css表中定义了许多默认样式 .同学在练习作业的过程中遇到样式问题 , 可以在浏览器中按F12多查看是否是bootstrap自带样式影响 .
并尝试自己动手完善一下样式 .这样可以提高自身的独立解决问题的能力 . 加油 !
祝学习愉快 ,望采纳
