This example demonstrates a CSS sprite-based icon system where two distinct states—overview and demographics—are rendered as background images with active-state variations, using offset positioning to switch between icons. The code relies on Compass’s sprite helpers and a Sass `@each` loop to generate the `.icons-overview` and `.icons-demographics` classes, while manually specifying `background-position` values (e.g., `20px -70px` and `20px 12px`) to align the correct sprite icons. The active states toggle background positions via pseudo-classes like `:active` and custom classes such as `.overview_active`. The implementation uses the `icons-sprite` mixin from Compass, with the sprite file referenced from an external asset path. No data or interactive behavior is present; it purely showcases static UI icon styling.
