为什么不切换？ [英] Why it does not toggle?

问题描述

我已经通过vedio turorial使用bootstrap尝试了它，但它并不令人担心



对于小型设备，navbar-header的按钮不会切换。



我尝试过：

 <   div    类  = 容器  >  
 
 <   div     class   =  row >  
 
 <   div     class   = 容器 >  
 
 <   div    < span class =code-attribute> class   =  navbar-header >  
 
 <   a     href   = ＃    class   =  navbar-brand >  Universal MEdia <   / a  >  
 
 
 
 
 <   span    类  =  icon-栏 >  <   / span  >  
 <   span     class   =  icon-bar >  <   / span  >  
 <   span     cl屁  =  icon-bar > ;  <   / span  >  
 
 
 <   / div  >  
 
 <   div     class   = 折叠navbar-collapse    id   =  mynav >  
 <   ul    类  =  nav navbar-nav >  
 <   li  >  <   a     href   = ＃ >  Hoome <   / a  >  <   / li  < span class =code-keyword>>  <   li  >  <   a     href   =  ＃ >  ABout <   / a  >  <   / li  >  <   li  >  <   a     href   = ＃ > 服务<   / a  >  <   / li  >  <   li  >  <   a     href   = ＃ > 课程<   / a  >  <   / li  >  <   li  >  <   a     href   = ＃ > 与我们联系<   / a  >  <  < span class =code-leadattribute> / li  >  <   / ul  >  
 <  < span class =code-leadattribute> / div  >  
 
 < ;   / div  >  
 
 <   / div  >  
 
 <   / div  >  

解决方案

如果您从视频教程中获得了代码，那么请返回YouTube（或教程来自的任何地方）并在那里询问。作者应该更好地了解他的代码如何工作 ^* 我们应该能够并且应该能够比我们更好地帮助你。





*假设这是他的代码，很多视频教程都是由那些不知道他们在做什么的人制作的。

			</div>

	</div>

</div>

解决方案

If you got the code from a video tutorial, then go back to YouTube (or wherever the tutorial came from) and ask there. The author should have a much, much better idea how his code works^* that we would and should be able to help you better than we could.


* Assuming it's his code, many video tutorials are produced by people who have no idea what they are doing.
