scss-shiny
A Binder example of integrating SCSS (and HTML) from CodePen into a Shiny Application

This example uses code from this CodePen repo to demonstrate how to convert Sass CSS into regular CSS, as well as some of the errors from the process.

# Copy-Paste the output of the following command into .css file
sass(sass_file("www/pingpong.scss"))
