Styling Customizability

You can change how the rendered tree looks like by providing custom CSS rules or changing CSS variables to customize its looks.

info

The default styles are declared here.

You can further customize how the tree looks like by providing custom render hooks to provide logic for rendering the individual DOM nodes. This customizability is further documented in the Render Hook Guide.
