This skill covers CSS file organization, naming, standard sizes, programmatic layout (SplitView, Grid, scrollable), responsive patterns, and text overflow handling. --- ## 1. File Organization CSS files are **co-located** with their TypeScript components: ``` src/vs/base/browser/ui/button/ button.ts button.css src/vs/workbench/contrib/myFeature/browser/ myFeature.ts media/ myFeature.css ``` Import CSS directly in the TS file: ```typescript import './media/myFeature.css'; // or for base widgets: import './button.css'; ``` Workbench-level global styles live in `src/vs/workbench/browser/media/`. ## 2.
