This is pretty wild: Adrian Roselli has made a series of rather complex Venn diagrams using nothing but CSS. With a combination of the Firefox dev inspector, plus a mixture of CSS Grid and the shape-outside
property, it’s possible to do this and without a ton of hacks, too.
I also think it’s super cute that Adrian has made the code snippets in this post look like the display from an old monitor, like the one Chris recently broke down.
