In our case, we were using
chunits to define our page layout. This meant that our post content was equal to50chunits (or the width of fifty0characters all lined up in a row).But the width of the

Cropping Images with CSS While Keeping a Focal Point in the Center
This is a lovely way to deal with image crop and focal point with CSS only! 😍 And I love that Johannes put this warning in the beginning: While client-side…
Apparently, an image whose part above the fold is indeed the largest, but of which only a small part can be seen, can be considered an LCP element, even if another image has a larger part visible... 😭

Do you know good tutorials and/or examples about dealing with responsive images that are fluid horizontaly, but with a fixed height?
Using object-fit: cover; in the CSS is easy, but how can we prevent loading many pixels that will be hidden, without using too many <source> in a <picture>?
Limiting the image density on mobile devices drasticaly improves performance, with no visual loss, so we did it!
I still wish it was much easier than dealing with <picture> and x descriptors for fluid images… 😞
With a <img maxdensity="2.5" …> attribute for example!

This is a real e-commerce site, with many real users everyday. After a few months of performance optimisation.
