{"version":"1.0","type":"rich","title":"Generated by SassMeister.com.","description":"This example demonstrates a color theme system generated entirely through Sass, where a single mixin applies background colors to a sequence of five span elements. The output shows how nested loops and list indexing produce a gradient effect, with each span receiving a progressively darker background from #555 to #111. Using Sass v3.4.1 and Compass v1.0.1, the code leverages the `@for` directive and the `nth()` function to iterate through predefined color and background lists. The rendering is purely CSS-based, with no JavaScript libraries or data sources involved.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-01485277124f992207c4?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
