Fun with grid-lanes - CSSDay 2026

A wind tunnel, with a plane inside, and smoke showing the air flow around it.

I want to give a quick analogy on this: The web doesn't evolve by writing specs in a vacuum, and sometimes agree on them. The web evolves because developers ask for things, try new things and experiment, and then complain loudly enough about them Specs happen later. It's a bit like a wind tunnel to test planes. Engineers who work on planes don't start by standardizing how to build them First, they build experimental prototypes. They shake them in wind tunnels. They see where things break in the real world, and discover turbulences. Only then do they write the rules for safe flight. The more we can be the web's wind tunnel, the better for our industry.
