    }
    .container {
      width: 100%;
      padding: 15px;
    }
    @media (min-width: 768px) {
      .container {
        width: 750px;
        margin: 0 auto;
      }
    }
    @media (min-width: 992px) {
      .container {
        width: 970px;
      }
    }
    @media (min-width: 1200px) {
      .container {
        width: 1170px;
      }
    }
  </style>
   

With this approach, your content will automatically adjust to fit the screen size, providing a seamless experience for users on any device.

Using Django REST Framework for APIs

Another powerful feature of Django is its REST framework. This framework allows you to build APIs that can be consumed by different types of clients, including web browsers, mobile apps, and IoT devices. By using Django REST framework, you can ensure that your application’s data and functionality are accessible from any device.

Here’s a simple example of how to create an API endpoint using Django REST framework:

  from .models import MyModel

  class MyModelSerializer(serializers.ModelSerializer):
      class Meta:
          model = MyModel
          fields = '__all__'

  class MyModelViewSet(viewsets.ModelViewSet):
      queryset = MyModel.objects.all()
      serializer_class = MyModelSerializer
   

By setting up API endpoints in this manner, you can ensure that your application’s core functionalities are available across different platforms and devices.

Here’s a basic example of custom middleware for device detection:

 
  class DeviceDetectionMiddleware:
      def __init__(self, get_response):
          self.get_response = get_response

      def __call__(self, request):
          user_agent = request.META.get('HTTP_USER_AGENT', '').lower()
          if 'mobile' in user_agent:
              request.is_mobile = True
          else:
              request.is_mobile = False
          response = self.get_response(request)
          return response
   

With this middleware, you can easily check the is_mobile attribute in your views and templates to provide a device-specific experience.
