Feature Indicator Size

Indicator thickness

Control how thick the underline indicator bar is.

Config key: indicator_size (top-level number, px) · Default: 3 · Range: 1–16

type: custom:tabdeck-card
style: underline
indicator_size: 6      # thicker underline
tabs: [ ... ]

Notes

• Applies to the underline style. For pill / segmented / boxed the indicator fills the whole tab, so thickness has no effect; text has no indicator.
• Values are clamped to 1–16; invalid values fall back to 3.
• Set it with the Indicator thickness (px) slider in the visual editor.
• The indicator colour follows accent_indicator / per-tab accent, or the theme --primary-color.
