Issues with Bootstrap Toggle Button functionality

I encountered a navbar error while working on my Django Project. After adding a few script tags, the navbar started to move down but did not return back to its original position. It worked fine before. By commenting out some script tags, it began to work again, so I am uncertain about what exactly is needed. Below is the HTML code. Thank you.

It seems like there might be a need to include some JavaScript files, but what exactly needs to be added is my main question.

<!DOCTYPE html>
<html lang="en">
  <head>
    {% load staticfiles %}
    <title>Cricket Management</title>
    ...
  </head>
  <body>
    <header>
      ...
    <footer class="text-muted">
      ...
    </footer>

</html>

Answer №1

Identified issues in your code leading to the problem:

  1. The inclusion of the Bootstrap 4 CDN in the head section.
  2. Also, calling Bootstrap JS files in the footer without proper order and dependency handling.
    1. Misplacement of proper.js, which is a prerequisite for Bootstrap 4, requiring jQuery before both.

Solution provided:

  1. Remove Bootstrap CDN declaration from the head section.
  2. Insert it towards the end of the page, just before the closing body tag.
  3. Ensure jQuery is loaded prior to Bootstrap's js and proper.js files.

  4. Avoid duplicate calls to any JS file, whether jQuery or Bootstrap files.

    Your code has been adjusted with these corrections. Please verify and keep note of the following checkpoints.

<!DOCTYPE html>
<html lang="en">
  <head>
    {% load staticfiles %}

    <!-- Rest of the HTML head content -->

  </head>
  <body>

    <!-- HTML header section content -->

    {% block content%}

      <!-- Main content section -->

    {% endblock content %}
    
    <footer class="text-muted">

      <!-- Footer content -->

    </footer>
  
    <script src="https://cdn.jsdelivr.net/npm/jquery@3.2.1/dist/jquery.slim.min.js"></script>
    <script src="https://cdnjs.cloudflare.com/ajax/libs/popper.js/1.11.0/umd/popper.min.js"></script>
    <script src="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0-beta/js/bootstrap.min.js"></script>

    <!-- Additional script file includes properly placed within the body tag -->

  </body>  

</html>
Your code has been revised to address the identified issues. Please review the changes made and ensure compliance with the outlined best practices.

  1. Repeated declarations of Bootstrap and jQuery CDNs before the body closure have been resolved.
  2. Footer placement corrected to be within the body tags as required by HTML structure.
  3. Usage of proper script tag for adding JS files implemented according to standards.
