Templates change the layout of your link in bio page. They're under the Design tab, separate from themes and fonts.
Switch templates
Open Page Editor.
Go to Design.
Pick a template. The preview updates, and it autosaves.
The templates
Fade — hero media at the top, widgets below. Optional profile picture.
Links — classic stacked links.
Banner — a banner image across the top.
Spotlight — full-bleed hero.
Scatter — Pro. Drag songs around with pill socials. No layouts, and no Profile List / Profile Stack.
A Full Site uses a different set: Spotlight, Tabs, Fade, and Links.
