Note: This plugin is just a temporary fix for the original plugin: https://www.npmjs.com/package/gitbook-plugin-styles-sass ! The only thing I did was to raise the node-sass version, when the original version works again I will most likely delete this package again!
This plugin makes it easy to use SASS custom stylesheets instead of CSS for your book.
Add it to your book.json, with some custom stylesheets:
{
"plugins": ["styles-sass"],
"styles": {
"pdf": "./styles/pdf.sass"
}
}
