I created this website with Django, which is a python based web framework.
If you want to see the documentation: Django .
It is hosted on ovhcloud.com.
The styling is done with css and a little bit of javascript

I used the following open-source libraries:
Pygments  to highlight text as code.
Pillow to watermark the pictures.
python-dotenv  to handle my environment variables.

The backend is MySQL.
I took the pictures with a Reflex Canon camera.
