bootstrap glyphicons are not working
<p>i downloaded bootstrap.min.css via NuGet Package manager into my project in visual studio and the glyphicons are not working(but all the other bootstrap functions work...) I referenced it in the layout page:<br>

When i wrote this it worked but only when i have internet access:
 
  
   
what can be the problem that the glyphicons don't show up and all the other bootstrap functions work? I want to be able to work on my project even if i'm not connected to the internet.
I'm new to all of this and i would really appreciate some help.</p>
