Inline your Critical CSS to eliminate render-blocking resources. This will speed up your store.
With Critical CSS, the visitor gets the base styling as quickly as possible; because it’s right there in a <style> element in the document’s <head>, there’s: no extra request to the server for the stylesheet & no waiting for the requested styles to load in and render. The below-the-fold, or non-critical, styling is then loaded in the background to avoid render-blocking.
Every number on this page comes from public storefront scans and the public Shopify App Store listing. If Shoplist shows Inline ‑ Critical CSS on a store, it is there.
