bootstrap课程13 bootstrap的官方文档中有一些控件的使用有bug，如何解决这个问题

一、总结

一句话总结：因为演示是正常的，所以检查演示效果的代码，把那一段相关的都弄过来就可以了

1、工具提示是怎么做出来的？

Hover over the links below to see tooltips:
data-toggle="tooltip" data-placement="top" title="Tooltip on top"
如果这个没有效果，就看它样例里面是怎么写的，如果把样例拿下来还不行，那就是差文件了，把js下下来就可以了

二、bootstrap的官方文档中有一些控件的使用有bug，如何解决这个问题

1、相关知识

滚动监听:
data-spy='scroll'
data-target='#mynav'
data-offset='150'

[自定义滚动监听实例]

标签页:
[data-toggle='tab']
.tab-content
.tab-pane
.active
.fade
.in

折叠效果:
[data-toggle="collapse"]
[data-parent='#accordion']
.panel-collapse
.collapse
.panel-group

幻灯片:
.carousel
.slide
[data-ride='carousel']
.carousel-inner
.item
.active
.carousel-indicators
[data-slide-to='0']
.left
.carousel-control
[data-slide='prev']
[data-slide='next']
