This way a guaranteed full integration between Varbase components and Varbase themes.

Varbase Components and SMACSS

All Varbase components organize CSS files under libraries with full use of SMACSS in mind.

A flexible guide to developing sites small and large.

SMACSS (pronounced “smacks”) is more style guide than rigid framework. There is no library within here for you to download or install. SMACSS is a way to examine your design process and as a way to fit those rigid frameworks into a flexible thought process. It is an attempt to document a consistent approach to site development when using CSS.

Inspected for Varbase components with basic or no styling to look better when Vartheme BS4 or a sub theme of it was the default theme for the site.

Vartheme BS4 too organize CSS files under libraries with full use of SMACSS in mind.


Drupal follows a SMACSS-style categorization of its CSS rules:

  1. Base — CSS reset/normalize plus HTML element styling.

  2. Layout — macro arrangement of a web page, including any grid systems.

  3. Component — discrete, reusable UI elements.

  4. State — styles that deal with client-side changes to components.

  5. Theme — purely visual styling (“look-and-feel”) for a component.

Refer to Drupal.org standards for CSS file organization (for Drupal 9)
