What could be causing a specific CSS class to not take effect?

Recently, I embarked on a journey to learn Django framework with Python. My main source of knowledge is a course I found on YouTube. However, I encountered an issue where the CSS and JS features were not applying to my page as demonstrated in the course.

Could you share some suggestions on how to rectify this issue so that the styles can be applied to my page? I was using the starter template provided.

Answer №1

It appears that you are utilizing Bootstrap CDN in your project. It's possible that the tutorial was created using an older version of Bootstrap (such as v3.0). However, the current version available on their website is v4.3.1. This means that some styles may not work as expected. For example, classes like img-circle and pull-right from Bootstrap 3 have been replaced with rounded-circle and float-right in the latest version.

If you wish to follow along with the tutorial, I suggest noting the specific version being used and incorporating that into your project. Alternatively, you can search online to determine if a CSS class exists in the latest version or if it has been renamed. Adapting to the new class names will ensure compatibility with Bootstrap's latest updates.
