Bootstrap tabs in Chrome extension popup

I have some Bootstrap tabs in my HTML file:

<!doctype html>

<script   src="https://code.jquery.com/jquery-3.1.1.min.js"   integrity="sha256-hVVnYaiADRTO2PzUGmuLJr8BLUSjGIZsDYGmIJLv2b8="   crossorigin="anonymous"></script>

<style type="text/css">
    #mainPopup {
        padding: 10px;
        height: 400px;
        width: 288px;
        font-family: Helvetica, Ubuntu, Arial, sans-serif;
    }
</style>

<html lang="en">

<div class="container" id="mainPopup">
    <ul class="nav nav-tabs">
        <li class="nav active"><a href="#A" data-toggle="tab">A</a></li>
        <li class="nav"><a href="#B" data-toggle="tab">B</a></li>
        <li class="nav"><a href="#C" data-toggle="tab">C</a></li>
    </ul>

    <!-- Tab panes -->
    <div class="tab-content">
        <div class="tab-pane fade in active" id="A">Content inside tab A</div>
        <div class="tab-pane fade" id="B">Content inside tab B</div>
        <div class="tab-pane fade" id="C">Content inside tab C</div>
    </div>
</div>
</html>

Here is the HTML being displayed in a webpage and in a Chrome extension:

The code in the browser allows me to change tabs, but the one in the Chrome browser extension one doesn't. What is the reason to this, and how can I get Bootstrap to work in the Chrome extension?

Solution

  • It turns out you can't link external Javascript files at the top of your HTML file. I had to download the Bootstrap files and save them locally in order for them to be used in an extension.
