Troubleshooting Problems with Bootstrap Navbar

I'm facing an issue with the background on the navbar of a website I am currently working on. The background works fine when expanded, but on the collapsed view, the button does not open the navbar as expected. Below is the code snippet that I have been using for the navbar. If you have any insights or ideas on why this may be happening, please share. Thank you!

<nav class="navbar navbar-default">
<div class="container-fluid">
<!-- Brand and toggle get grouped for better mobile display -->
<div class="navbar-header">
  <button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#bs-example-navbar-collapse-1" aria-expanded="false">
    <span class="sr-only">Toggle navigation</span>
    <span class="icon-bar"></span>
    <span class="icon-bar"></span>
    <span class="icon-bar"></span>
  </button>
  <a class="navbar-brand" href="index.html"><img src="http://entropymag.org/wp-content/uploads/2014/10/outer-space-wallpaper-pictures.jpg" height="25" width="40"></a>
</div>

<!-- Collect the nav links, forms, and other content for toggling -->
<div class="collapse navbar-collapse" id="bs-example-navbar-collapse-1">


  <ul class="nav navbar-nav navbar-center">
    <li><a href="about.html">About</a></li>
    <li><a href="contact.html">Contact</a></li>
    <li><a href="resume.html">Skills</a></li> 

  </ul>

</div><!-- /.container-fluid -->

Answer №1

It appears that bootstrap.js was not included in your code

<!-- Make sure to include the Latest compiled and minified JavaScript for Bootstrap -->
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/js/bootstrap.min.js" integrity="sha384-0mSbJDEHialfmuBBQP6A4Qrprq5OVfW37PRR3j5ELqxss1yVqOtnepnHVP9aJ7xS" crossorigin="anonymous"></script>

Answer №3

If you're facing issues with your navbar code, there are a few potential reasons why this might be happening. First off, ensure that you include Bootstrap's JavaScript file as suggested by other answers. Additionally, it's crucial to have jQuery included for Bootstrap's JavaScript functionality to work properly. Remember to load jQuery's library before including Bootstrap's JavaScript. Your navbar code appears correct, so the problem likely lies in one of these areas. Make sure to include both jQuery and Bootstrap's JavaScript, prioritizing jQuery's loading first. Here is an example of how everything should be structured:

<!DOCTYPE html>
<html lang="en>
  <head>
    <meta charset="utf-8">
    <!-- Latest compiled and minified Bootstrap CSS -->
    <link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/css/bootstrap.min.css" integrity="sha384-1q8mTJOASx8j1Au+a5WDVnPi2lkFfwwEAa8hDDdjZlpLegxhjVME1fgjWPGmkzs7" crossorigin="anonymous">
    <!-- Latest compiled and minified Jquery JavaScript This needs to be before bootstraps javascript -->
    <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.2.0/jquery.min.js"></script>
    <!-- Latest compiled and minified Bootstrap JavaScript -->
    <script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/js/bootstrap.min.js" integrity="sha384-0mSbJDEHialfmuBBQP6A4Qrprq5OVfW37PRR3j5ELqxss1yVqOtnepnHVP9aJ7xS" crossorigin="anonymous"></script>
  </head>
  <body> 
    <nav class="navbar navbar-default">
      <div class="container-fluid">
      <!-- Brand and toggle get grouped for better mobile display -->
      <div class="navbar-header">
        <button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#bs-example-navbar-collapse-1" aria-expanded="false">
          <span class="sr-only">Toggle navigation</span>
          <span class="icon-bar"></span>
          <span class="icon-bar"></span>
          <span class="icon-bar"></span>
        </button>
        <a class="navbar-brand" href="index.html"><img src="http://entropymag.org/wp-content/uploads/2014/10/outer-space-wallpaper-pictures.jpg" height="25" width="40"></a>
      </div>

      <!-- Collect the nav links, forms, and other content for toggling -->
      <div class="collapse navbar-collapse" id="bs-example-navbar-collapse-1">


        <ul class="nav navbar-nav navbar-center">
          <li><a href="about.html">About</a></li>
          <li><a href="contact.html">Contact</a></li>
          <li><a href="resume.html">Skills</a></li> 

        </ul>
      </div><!-- /.navbar-collapse -->
      </div><!-- /.container-fluid -->
    </nav>
  </body> 
</html>

You have the option to link your CSS and JavaScript files locally or use CDNs like the ones shown above. For convenience, I've utilized CDNs so you can simply copy and paste this code to see it in action. Hopefully, this clarifies any confusion you were experiencing.
