Automatic CSS subsetting for `{% stylesheet %}` tags
UpdateUnverifiedAdded Sep 24, 2026
Shopify is introducing CSS content subsetting for {% stylesheet %} tags to improve storefront performance. Starting April 20, 2026, Shopify only delivers the CSS from {% stylesheet %} tags that are relevant to the sections, blocks, and snippets rendered on each page, instead of serving all {% stylesheet %} CSS on every page load.
