doing some housekeeping to the code

[Viterbo]

Fixes #636

Description

There are lots of places where the code should be prepared from a bad indentation or bad practice. This PR fixes all indentation problems and some minor refactor as well.

Test scenarios

No behavior should be changed. Open in parallel the current dev site and this branch in different tabs. Browse both at the same time. You should not see any difference.
