Standardizing a Style Guide. Essentially the names drafted for this framework are issued to the Style Guide, instead of a primer on CSS. So a dependency is on metaprogramming CSS with preprocessors; then the use of frameworks or package managers (!) for deploying CSS fragments/modules along with the Hypermedia API.

theme.scss

// @import "theme-front";

/* UI System
 *
 * #note hoisting
 */

.#{$ui} {
  background: transparent;

  .columns { 
    // What did the Front have to say?
  }
}

/* Design Implementation
 *
 * @implements bones
 * @note hoisting
 */

.#{$theme} {
  background: url('http://placeanything.com/pics/150/150/') center top;
  // @import "theme-header";
  // @import "theme-footer";
  // @import "theme-bones";
}
