Netlify is announcing its `Inline Critical CSS` build plugin, which automatically extracts and inlines critical CSS of a webpage to render content faster. The plugin was contributed by Tom Bonnike, an engineer at Shopify, and can be used with other plugins like the `Inline Source` plugin to speed up content delivery even further. By inlining critical CSS directly into the HTML document, this plugin eliminates additional requests and delivers a "one roundtrip" critical path where only the HTML is a blocking resource. This can be particularly beneficial for websites using the Jamstack for speedy content delivery.
