SASS Processing with Hugo Pipes Janne Kemppainen | June 8, 2020

So far we have been using the CDN version of Bulma. However, this has the unfortunate property that we cannot really customize the colors and other parameters. We can solve this by using Hugo pipes to process the Bulma source code with the built-in SASS processor.
