gitbook-plugin-bottom-navigation

In your book.json, make sure bottom-navigation is defined before any other footer plugin.

{
  "plugins": [
    "bottom-navigation",
    "page-footer-ex"
  ]
}

You can customize the hovered color with following properties (all properties are listed in packages.json):

{
  "pluginsConfig": {
    "bottom-navigation": {
      "iconColor": null,
      "titleColor": null,
      "borderColor": "#3884FE"
    }
  }
}

Note borderColor has the highest priority which means if iconColor or titleColor is not defined, it will be the same color with borderColor.

If you think default width of page-inner is too narrow, you can change it with pageInnerWidth property like "pageInnerWidth": "80%".

The path attribute in page object is not parsed to html. I get the parsed path through default navigation class. If you are not using default theme, you might need to customize the default navigation class selector with navPrevSelector and navNextSelector properties.
