At the moment, Bulmil is using bulma's scss variables (bulma-scss) to style stencil components.

However, as components are built & then distributed, it becomes impossible to customize the styles dynamically.

Using CSS variables will solve this issue, I'm currently working on an alternative, apparently, it is also a proposed feature in Bulma:

• Feature: Support CSS Custom Properties (Variables) jgthms/bulma#1837
