very generic question. I am super confused on how to use SASS in Magento 2, I can't seem to find an easy guide on explaining step by step how to do so... any help is appreciated. Thanks!
by default, magento2 only supports less.
at first, you would have to install the sass blank theme from snowdog: https://github.com/SnowdogApps/magento2-theme-blank-sass
If you are using the theme, you might also want to use the frontools extension for an optimized workflow: https://github.com/SnowdogApps/magento2-frontools
The whole project got picked up by magento as less to sass community project. You can find more information in the magento forum: https://community.magento.com/t5/Less-to-Sass-Community-Project/bd-p/less-to-sass
