Should style/index.js import index.css instead of base.css ?

[Carreau]

I have no clue, maybe I[m doing things wrong,] but any modif I do to index.css of an extension have no effect. It does if I apply them to base... that is unless I cahnge style/index.js to import from index and not base.

The index.css/index.js mechanism comes from difficulties to tree shake styles in JupyterLab.

Long story short, the practice is to keep things as in this cookiecutter (aka index.css and index.js import base.css). And place your style in base.css.

Ok, I'll see if I can make a pull request that explain this in index.css.
