css - Navbar collapse navigation not functioning -


i hoping can me figure out why collapse in bootstrap navbar isn't working. have seen bootstrap examples, should work. when view page on mobile device or shrink window, nav links collapse should, button expand not show up.

<nav class="navbar">     <div class="container">     <div class="navbar-header">         <button type="button" class="navbar-toggle" data-toggle="collapse" data-target=".navbar-ex1-collapse"> <span class="sr-only">toggle navigation</span> <span class="icon-bar"></span> <span class="icon-bar"></span> <span class="icon-bar"></span> </button>         <a href="#" class="pull-left"><img src="/images/logo.png"></a> </div>     <div class="navbar-collapse collapse">         <div class="navbar-right"><a href="/contact">contact</a></div>         <div class="navbar-right"><a href="/about">about</a></div>         <div class="navbar-right"><a href="/ourteam">our team</a></div>         <div class="navbar-right"><a href="/work">work</a></div>         <div class="navbar-right"><a href="/services">services</a></div>     </div>     </div> </nav>

edit

i went through comments , checked everything. there issue jquery not loading, resolved that. still happening though.

i trying split utf-8 string bytes in python 3. problem is, when use bytearray, byte, encode etc functions array size of element 14 bytes, not 1 byte expected. need split text file sequence of bytes , send them byte after byte using sockets. tried this: infile = open (file, "r") str = infile.read() byte_str = bytes(str, 'utf-8') print("size of byte_str",sys.getsizeof(byte_str[0])) print gives me 14, need 1... suggestion? quoting official documentation : sys.getsizeof(object[, default]) return size of object in bytes. object can type of object. built-in objects return correct results, not have hold true third-party extensions implementation specific. only memory consumption directly attributed object accounted for, not memory consumption of objects refers to. if given, default returned if object not provide means retrieve size. otherwise typeerror raised. getsizeof() calls object’s __sizeof__ method , adds
