Deprecating Sass in themes
Themes
Effective November 04, 2020
Action required
The use of .scss files within compiled Shopify themes is being officially deprecated. We'll be transitioning to only using .css files within all free and paid themes available on the Shopify Theme Store.
Support for Sass won't be removed in the short term and themes using .scss files will continue to function. However, we strongly recommend that developers compile their .scss files to .css locally, or use only .css files. New themes might be blocked from using .scss files in the future.
To learn more about this change and the alternatives available for developers who want to continue using Sass in their development workflow, refer to the Shopify Partners Blog.
