CSS style is missing in all my Django applications
<p>Since I started using the Django framework I noticed that the CSS style did not appear when I entered the admin site and others templates and I thought it was normal but with the passage of time I have seen that the applications of my partners did have the style, so I copied their projects on my laptop and I ran them and I could see the CSS style of their applications.
I'm getting data from a database from a server, that's the only difference in how my partners and I have been working.</p>

<p>Does anyone know how I can fix this?</p>

<p>PD: I'm working with version 1.8 of Django and version 3.4.4 of python </p>

<p>This is my base of my HTML's code</p>

<pre><code>{% load staticfiles %}
&lt;html&gt;
    &lt;head&gt;
        &lt;title&gt;DENUE INEGI&lt;/title&gt;
        &lt;link rel="stylesheet" href="//maxcdn.bootstrapcdn.com/bootstrap/3.2.0/css/bootstrap.min.css"&gt;
        &lt;link rel="stylesheet" href="//maxcdn.bootstrapcdn.com/bootstrap/3.2.0/css/bootstrap-theme.min.css"&gt;
        &lt;link href='//fonts.googleapis.com/css?family=Lobster&amp;subset=latin,latin-ext' rel='stylesheet' type='text/css'&gt;
        &lt;link rel="stylesheet" href="{% static 'css/crm.css' %}"&gt;
    &lt;/head&gt;
    &lt;body&gt;
        &lt;div class="page-header"&gt;
            {% if user.is_authenticated %}
            {% else %}
                &lt;a href="{% url 'login' %}" class="top-menu"&gt;&lt;span class="glyphicon glyphiconlock"&gt;&lt;/span&gt;&lt;/a&gt;
            {% endif %}
                &lt;h1&gt;&lt;a href="/"&gt;Directorio Estadístico Nacional de Unidades Económicas INEGI&lt;/a&gt;&lt;/h1&gt;
        &lt;/div&gt;
        &lt;div class="content container"&gt;
            &lt;div class="row"&gt;
                &lt;div class="col-md-8"&gt;
                    {% block content %}
                    {% endblock %}
                &lt;/div&gt;
            &lt;/div&gt;
        &lt;/div&gt;
    &lt;/body&gt;
&lt;/html&gt;

<p>Here is my setting.py file</p>

<pre><code>TEMPLATES = [
{
    'BACKEND': 'django.template.backends.django.DjangoTemplates',
    'DIRS': [os.path.join(BASE_DIR,'templates')],
    'APP_DIRS': True,
    'OPTIONS': {
        'context_processors': [
            'django.template.context_processors.debug',
            'django.template.context_processors.request',
            'django.contrib.auth.context_processors.auth',
            'django.contrib.messages.context_processors.messages',
        ],
    },
},
]

# Static files (CSS, JavaScript, Images)

STATIC_URL = '/static/'
STATIC_ROOT = os.path.join(BASE_DIR, 'static')
LOGIN_REDIRECT_URL = '/'
