Hello Worldin' Some Web Component Libraries

Sometimes you just gotta try the thing to get to know the thing a little bit. Chris had bookmarked one he saw called Tonic, so we muscled our way through that with a smidge of templating and state management, then did the same thing in Lit, then did it again in petite-vue.

Breakin' Up CSS Custom Properties

Why not take every major styling choice on a particular component and make it into a custom property? Then, when you need a variation, you can just change the custom property and not re-declare the entire ruleset. This has some nice advantages, like clearly presenting a menu of things-to-change and not needing to dig into subcomponents to re-style variations.

An arctic, north-bluish color palette.
