Overview

This section is a work in progress, but listed below are the available CSS variables for styling elements. Types are not provided as these are traditional CSS parameters.

These variables can be passed as styling props to individual components or used to create global themes using a selector with the following structure: :root[svelvet-theme="theme-name"].

These theme names can be passed to the Svelvet component via the reactive theme prop and to the Theme Toggle component via the main and alt props.

When passing to individual components, these styles are scoped to the component itself. This is not currently true of Edges and our recommendation is to create custom Edge components.

Scroll to the bottom for example code.

You can style parameters beyond those available here by using global selectors. :global(.svelvet-node) applies to all Nodes, for instance. Will add all internal class names with time!
