Autocomplete and hover documentation for Base UI data attributes and CSS variables — directly in your CSS, SCSS, and Less files.
Install from the VS Code Marketplace.
When you write CSS attribute selectors or custom property values targeting Base UI components, this extension gives you completions and inline docs without leaving your editor. Type [data- to see all Base UI data attributes with descriptions, pick one, then get value completions for enumerated options like top | bottom | left | right. Hover any Base UI --variable or [data-*] selector to see which components use it and jump straight to the source on GitHub.
CSS, SCSS, Less
The extension automatically detects which version of @base-ui/react is installed in your workspace and fetches the matching data from GitHub. The fetched data is cached locally so subsequent startups are instant and offline use still works.
If no data exists for your exact version, the extension falls back to its bundled dataset and logs a message to the Base UI IntelliSense output channel explaining which version is in use.
Issues and PRs welcome at github.com/IdoS350/base-ui-css-intellisense.
