Eliminate render-blocking resources

Info

View all occurrences

Resources in the head block first paint until they download. Defer or inline critical CSS.

Render-blocking resources in <head> delay first paint until the browser downloads and parses them. Every kilobyte adds latency, especially on slow networks.

Lighthouse: Eliminate render-blocking resources web.dev: Defer non-critical CSS

Recommended

<!-- Defer non-critical scripts -->
<script src="analytics.js" defer></script>

<!-- Async for independent scripts -->
<script src="ads.js" async></script>

Avoid

<!-- Blocks parsing until downloaded -->
<script src="jquery.js"></script>
