[tox] Drop "exclude" option from flake8 config and adjust flake8-ok-files.txt accordingly
Some files listed in flake8-ok-files.txt were excluded of flake8 run because
of the "exclude" option in tox.ini. Some of them were non-existent files
(moved), some others were actually non-flake8-compliant. In the latter case,
we adjust trivial errors (blank lines, module import not on top of file) but
remove others (like cubicweb/test/unittest_utils.py) from
flake8-ok-files.txt.
CSS Coding Standards
--------------------
(Draft, to be continued)
:Naming: camelCase
Indentation rules
~~~~~~~~~~~~~~~~~
- 2 espaces avant les propriétés
- pas d'espace avant les ":", un espace après
- 1 seul espace entre les différentes valeurs pour une même propriété
Documentation
~~~~~~~~~~~~~
Please keep rules semantically linked grouped together, with a comment about
what they are for.
Recommendation
~~~~~~~~~~~~~~
- Try to use existing classes rather than introduce new ones
- Keep things as simple as possible while in the framework
- Think about later customization by application
- Avoid introducing a new CSS file for a few lines of CSS, at least while the
framework doesn't include packing functionalities
