Documentation

When python docs are viewed in dark theme, code snippets are put against a light colour background. This makes white letters unreadable. Please see attached screenshot.

This screenshot was taken at: https://docs.python.org/3.8/library/csv.html

Steps to reproduce:

1. Visit https://docs.python.org/3.8/library/csv.html
2. Select theme "Dark" from the drop down menu in the top right corner.
3. Scroll to see any code snippet.
