FITstagram

I created a small LQIP (low-quality image placeholder) script on https://vitapavlik.cz/fekt_mapa/

Phase 1: ~60 kB of resources are loaded
Phase 2: ~250 kB of resources are loaded
Phase 3: ~8000 kB of resources are loaded

The middle step could be omitted for people with fast internet, but oh well.

Aditionally, I converted all images to webp (previously it was ~12 MB of jpgs and pngs).

Now the page will be usable for people with slow connection. And because that site, just like FITstagram, allows both HTTP/2 and HTTP/3, there is no head-of-line blocking and people with fast connection will likely notice no difference 😎
