Why bootstrap doesn't work although I have loaded it, etc. (Django project)?
<p>I'm working on this Django project. The functionality works perfectly fine. When I started working on the front-end using Bootstrap3, I ran into some issues (more like confusions). </p>

<p>First, I installed django-bootstrap3 using command prompt like so:</p>

<pre><code>pip install django-bootstrap3
</code></pre>

<p>The installation was successful. Bootstrap3 was downloaded into this location in my computer <em>c:\python34\lib\site-packages</em> Then, I included it as a third-party app in  <strong>settings.py</strong> in the list of <em>INSTALLED_APPS</em> in my main project directory like so:</p>

<pre><code> INSTALLED_APPS =(
--apps--
'bootstrap3',
)
</code></pre>

<p>Also in <strong>settings.py</strong>, I included jQuery like so:</p>

<pre><code>BOOTSTRAP3 = {'include_jquery': True}
</code></pre>

<p>I modified my <em>base.html</em> to include the bootstrap elements. I have two apps, <em>users</em> and <em>mynotess</em> (sorry for bad naming)</p>

<p><strong>base.html</strong></p>

<p><strong>EDIT</strong>: base.html is at the bottom of question.</p>

<p>For some reason, I loaded up <em>localhost:8000</em> and it was still in the normal ugly HTML form. I checked online, and I found some CDN links and thought maybe if I just used the CDN links, it would work.</p>

<p>I then included this in <strong>base.html</strong>, copied right from Bootstrap's website.</p>

<pre><code>&lt;link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css" integrity="sha384-BVYiiSIFeK1dGmJRAkycuHAHRg32OmUcww7on3RYdg4Va+PmSTsz/K68vbdEjh4u" crossorigin="anonymous"&gt;

</code></pre>

<p>(I included the links in the <em>head</em> section and the scripts in the <em>body</em> section of the HTML document).</p>

<p>It worked! <strong>However</strong>, when I <strong>removed the bootstrap3 from my INSTALLED_APPS</strong> and all the code that loads up bootstrap3 that was installed on my computer (such as <em>{% load bootstrap3 %}</em>, it didn't work. It went back to the ugly HTML format. Similarly, when I <strong>removed the CDN links</strong> and kept all the bootstrap3 code that loaded bootstrap installed on my computer, it went back to the ugly HTML format as well.</p>

<p>My question is:</p>

<ul>
<li><p>Is it supposed to be like this? According to a book that I'm currently following for this project, I don't even have to include the CDN links and scripts (the book doesn't mention them <strong>at all</strong>) and it ought to work.</p></li>
<li><p>If it's not supposed to be like this, is there something wrong with my code that's causing this? Am I missing some step? Are my bootstrap3 files in the correct directory? (i just downloaded it using pip through command prompt and I didn't move it anywhere else)</p></li>
</ul>

<p>The functionality of my Django website works just fine.
Any help, explanations, or suggestions are greatly appreciated!</p>

<p><strong>EDIT</strong>:
<strong>base.html</strong> would have to be like this if I wanted the Bootstrap elements to show up.</p>
