gitbook-plugin-header-anchorjs v1.1.2

Anchor.js for Gitbook

Adds deep links to headlines.

{
  "plugins": ["anchorjs"]
}

The deep links to page sections are initially-hidden and pop into view on hover. Design and behavior can adjusted in book.json:

{
  "pluginsConfig": {
    "anchorjs": {
      "icon": "#",
      "placement": "left",
      "visible": "always",
      "class": "custom-class another-one"
    }
  }
}
