How to Use Your Critical CSSPaste the generated CSS inside a <style> tag within the <head> of your HTML document. Place it high up, before any other stylesheets or blocking scripts.Remember you might need to change references to images or other assets<style> /* ... Critical CSS will appear here ... */ </style>Place your original non-critical CSS <link> tags just before the closing </body> tag. This allows the browser to render the initial content styled by the critical CSS first. Remember to remove these same links from your <head>!<html> ... <body> ... <link rel="stylesheet" href="/css/vendors.min.css"> <link rel="stylesheet" href="/css/style.min.css"> </body> </html>Alternatively, for potentially more optimized loading (especially on slow connections), use JavaScript in the <head> to load non-critical styles after the page content loads. Use this instead of Step 2. Update the stylesheets array and ensure the original links are removed from <head>.window.addEventListener("DOMContentLoaded", function () { console.log("Page loaded, now loading non-critical stylesheets..."); let stylesheets = [ ]; let loadedCount = 0; function checkAllStylesLoaded() { loadedCount++; if (loadedCount === stylesheets.length) { console.log("All non-critical stylesheets loaded..."); } } stylesheets.forEach(function (href) { var link = document.createElement("link"); link.rel = "stylesheet"; link.href = href; link.onload = checkAllStylesLoaded; link.onerror = () => console.warn("Failed to load stylesheet: " + href); document.head.appendChild(link); }); });
