Daniel Post shared a really cool performance-optimisation trick for Eleventy on Twitter the other day. When statically generating your site you can loop through your pages and, for each, use PurgeCSS to find the required CSS, then inline that into the <head>. This way, each page contains only the CSS it needs and no more!

Check out the code.

I’ve just installed this on my personal site. I was already inlining my CSS into the <head> but the promise of only including the minimum CSS that each specific page needs was too good to resist.

Turned out it was a breeze to get working, a nice introduction to Eleventy transforms, and so far it’s working great!

When should you add the defer attribute to the script element? (on Go Make Things)

For many years I’ve placed script elements just before the closing body tag rather than in the <head>. Since a standard <script> element is render-blocking, the theory is that by putting it at the end of the document – after the main content of the page has loaded – it’s no longer blocking anything, and there’s no need to wrap it in a DOMContentLoaded event listener.

It turns out that my time-honoured default is OK, but there is a better approach.
