Is this increasing complexity in the Web layout world worth it? Anyone who wants to use this is going to drop support for older browsers (and, in so doing, older machines that can't run newer OSes and newer browsers).
Personally, I use an 11-year-old machine and have had to add userscript hacks to certain major Web sites to work around bugs in CSS grid (not the "lanes" described here).
At least new JavaScript features can be "polyfilled" or whatever. Maybe sites could check for CSS feature support too? But they seem not to.
For example, the demo page linked in the article fails pretty unusably for me. All the images take up nearly the full viewport width.

Certainly can: https://developer.mozilla.org/en-US/docs/Web/CSS/Reference/A...
I don't think the world needs to cater to people that refuse even basic internet hygiene.
