Hi all,

I recently introduced a [PR](https://github.com/aiidalab/aiidalab-widgets-base/pull/624) proposing the use of external stylesheets _mostly_ in-place of `ipywidgets`’s layout API. I find CSS in general far more useful, flexible, and friendly for our purposes.

I personally use the SCSS flavor of stylesheets due to the power and flexibility they afford to the developer. There is nothing I can add that isn’t already covered by their [basic](https://sass-lang.com/guide/) guide.

This post is meant to get the feel of the AiiDAlab development team regarding switching to SCSS/CSS. Note that there is a compilation step (SCSS → CSS) that has to be addressed in a reasonable manner. My PR proposes one (I don’t care for it). Input welcomed!
