Styling

Target the track with [huey-slider="alpha"] (or the shared [huey-slider-track]) and its thumb with [huey-slider="alpha"] [huey-slider-thumb]. Use [aria-orientation="vertical"] to style the vertical orientation.

Property	Default	Description

--huey-slider-track-width	129px	Track width (or height when vertical)
--huey-thumb-size	var(--huey-slider-track-height, 16px)	Size of the thumb

The track background and thumb color are driven dynamically via --huey-slider-bg and --huey-thumb-color.
