# Deprecating Sass in themes

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](https://www.shopify.com/partners/blog/deprecating-sass).
