> What good use cases would you see for grid lanes today?

Fully responsive layouts, where sidebar content is interleaved with page content on small screens, but in a sidebar on larger screens.

Demo: https://codepen.io/pbowyer/pen/raLBVaV

Reordering the content on larger screens would be the icing on the cake but for now I'll take just doing it.

CSS Grid didn't solve this, as it added gaps: https://codepen.io/pbowyer/pen/azNarbZ

And using named grid-template-areas stacks the items you move to the sidebar on top of each other, so you only see one of them at a time. Eventualy I hope that https://github.com/w3c/csswg-drafts/issues/9098 will land and we'll be able to use this saner way to do it.

You can't debug it in anything other than a mac

This

I have users that have issues with Safari, CSS and Javascripts ones.

I MUST own an Apple device to debug anything.

I'm sorry but as a Free Software Web Developer I can't spend 2K€ on a Mac to just fix a CSS issue.

Frequently, but not always, I can reproduce such bugs using Epiphany [1] or other WebKit based browsers.

That's at least somewhat cheaper when it works.

You can buy a refurb Mac mini for €589. Macs haven't started at €2K since the early 90s.

You can also buy a used-like-new one on eBay for half that

When I was making money as a developer I purchased wintel systems to verify my work. I thought of it as the cost of doing business. Many Macs cost less then 2K euros.

A Mac mini is pretty affordable.

Also you can use browserstack.

More like $200-300 for a used M1 mini or Air…

Or free to just run macOS in a VM if you don’t care about breaking an EULA you never signed in the first place…

They are all telling you "Just buy a mac". Exactly the point that you and I were downvoted for saying.
