Slider
A value picked by dragging along a track, when an exact number is not needed.

See it live
npm run storybookWhen to use it
In Dense data: Narrows a filter to a range of risk scores by dragging.
- Use it when: Volume, brightness, a rough range; pair with a number field when precision matters.
- Not when: An exact answer people must type.
Instead:
- Input: An exact number.
- Radio group: A few named choices.
Words
- Lead with the object, then the state: "Alert 2041 contained."
- Use numbers, not words for numbers.
- One verb per button. No "please", no exclamation marks.
- Use: Investigate, Filter, Assign, Escalated, Resolved. Avoid: Oops, Awesome, Please, Simply.
The labels components use, from the voice tokens:
content.action.commit: Savecontent.action.cancel: Cancelcontent.action.destroy: Deletecontent.action.retry: Retrycontent.action.empty-action: Change filters
See Voice and tone for the whole voice.

npx open-ds add slider
The component reads only component keys and semantic tokens, so it follows the brand and mode on <html>.
Tokens it reads
Slider reads 13 tokens of its own, each an alias of a semantic token. Each row is one part: its own token, the semantic it aliases, and the value it ends at. Change a semantic and every component that reads it follows; override one of Slider's tokens to change Slider alone.
Dense data decides what changes when you switch theme. Here a switch changes colors only, so the marked rows differ between light and dark; everything else holds steady.
