Render-Blocking Resources

Scripts and stylesheets that delay first paint until they finish loading.

CSS and synchronous JavaScript in the document head block rendering until processed. Solutions include async/defer attributes on scripts, critical CSS inlining, removing unused CSS, deferring non-essential JS and using preload for important resources. Modern Wix sites apply most of these optimisations automatically.
