Why Are CSS Styles from base.html Not Applied in My Django index.html?

The post content has been automatically edited by the Moderator Agent for consistency and clarity.

I'm working on a Django project where my index.html file extends base.html. CSS and JavaScript applied in base.html work perfectly, but the same CSS is not taking effect in index.html.

I can add and edit CSS styles in base.html, and they are shown as expected. However, when I extend base.html in index.html, the CSS code doesn’t seem to work. I've verified that the routes and settings.py have been configured correctly, but the styles still don't apply in index.html.

Below are the relevant file contents:

style.css

CSS
.ball {
  position: absolute;
  border-radius: 100%;
  opacity: 0.7;
}

#carouselExample {
    height: 300px;
    width: 300px;
}

The CSS and JS in base.html work correctly, but when index.html extends this base, the styles don't seem to apply. Does anyone have suggestions on why the CSS might not be working for index.html?

Django Template Inheritance CSS Issue

I've identified several issues with your template structure that are likely causing your CSS not to apply correctly in the extended template.

Main Issues

  1. Incorrect Template Structure: When using template inheritance in Django, you should only include HTML structure elements (like <link>, <script>, etc.) within the appropriate blocks defined in the base template.

  2. Duplicate CSS Loading: You're loading the same CSS files in both templates, but the ones in index.html are outside any block, making them ineffective.

How to Fix It

1. Modify your base.html

Your base template should include blocks for head content:

HTML
{% load static %}
{% load blog_tags %}

<!doctype html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, user-scalable=no, initial-scale=1.0, maximum-scale=1.0, minimum-scale=1.0">
    <meta http-equiv="X-UA-Compatible" content="ie=edge">
    
    <link href="https://cdn.jsdelivr.net/npm/bootstrap@5.3.3/dist/css/bootstrap.min.css" rel="stylesheet" integrity="sha384-QWTKZyjpPEjISv5WaRU9OFeRpok6YctnYmDr5pNlyT2bRjXh0JMhjY6hW+ALEwIH" crossorigin="anonymous">
    <script defer src="https://use.fontawesome.com/releases/v5.15.4/js/all.js" integrity="sha384-rOA1PnstxnOBLzCLMcre8ybwbTmemjzdNlILg8O7z1lUkLXozs4DHonlDtnE7fpc" crossorigin="anonymous"></script>
    <link rel="stylesheet" href="{% static 'blog/css/style.css' %}">
    
    {% block extra_css %}{% endblock extra_css %}
    
    <title>
        {% block title %}{% endblock title %}
    </title>
</head>
<body>
    <!-- Rest of your base template -->
    
    {% block main %}{% endblock main %}
    
    <script src="{% static 'blog/js/snow.js' %}"></script>
    <script src="https://cdn.jsdelivr.net/npm/bootstrap@5.3.3/dist/js/bootstrap.bundle.min.js" integrity="sha384-YvpcrYf0tY3lHB60NNkmXc5s9fDVZLESaAA55NDzOxhy9GkcIdslK1eN7N6jIeHz" crossorigin="anonymous"></script>
    
    {% block extra_js %}{% endblock extra_js %}
</body>
</html>

2. Modify your index.html

Your index template should only include content within the defined blocks:

DJANGO
{% extends 'base.html' %}
{% load static %}
{% load blog_tags %}

{% block extra_css %}
<!-- Add any additional CSS specific to this page -->
{% endblock extra_css %}

{% block title %}
{{ main_page }}
{% endblock title %}

{% block main %}
<div class="hero-section" style="background-image: url(https://cdn.trend.az/2024/09/09/air-products.png);
height:750px;
background-repeat:no-repeat;
background-size:cover;">
    <div class="row">
        <div class="col-6">
            <h1 style="margin-top:150px"><strong>Industrial Gas Supplier</strong></h1>
        </div>
    </div>
</div>






<div id="carouselExample" class="carousel slide">
  <div class="carousel-inner">
    <div class="carousel-item active">
      <img src="https://www.newscentralasia.net/wp-content/uploads/2023/09/air-products-co.jpg" class="d-block w-100" alt="...">
    </div>
    <div class="carousel-item">
      <img src="https://www.gasworld.com/cdn-cgi/image/width=1200,height=900,fit=contain,quality=75,metadata=none,format=auto,gravity=auto/https://www.gasworld.com/wp-content/files/gwml/actros2545airproducts21_185696.jpg" class="d-block w-100" alt="...">
    </div>
    <div class="carousel-item">
      <img src="..." class="d-block w-100" alt="...">
    </div>
  </div>
  <button class="carousel-control-prev" type="button" data-bs-target="#carouselExample" data-bs-slide="prev">
    <span class="carousel-control-prev-icon" aria-hidden="true"></span>
    <span class="visually-hidden">Previous</span>
  </button>
  <button class="carousel-control-next" type="button" data-bs-target="#carouselExample" data-bs-slide="next">
    <span class="carousel-control-next-icon" aria-hidden="true"></span>
    <span class="visually-hidden">Next</span>
  </button>
</div>
{% endblock main %}

{% block extra_js %}
<!-- Add any additional JS specific to this page -->
{% endblock extra_js %}

Key Points to Remember

  1. Remove Duplicate Elements: Don't include <link> or <script> tags outside of blocks in your extended templates.

  2. Use Block Structure: All content in the child template should be inside blocks defined in the parent template.

  3. Static Files Loading: The {% static %} tag should be used within the appropriate blocks.

  4. Check Static Files Path: Ensure your CSS file is correctly located at blog/static/blog/css/style.css in your app directory.

  5. Development Server: If you've made changes to static files, restart your development server with python manage.py runserver to ensure the changes are picked up.

If you're still experiencing issues after these changes, check your browser's developer tools to see if there are any errors loading the CSS file or if there are CSS rules that might be overriding your styles.
