Select it! - Styling new HTML UI capabilities

We are getting spoiled with increased UI capabilities, partially thanks to the efforts from the W3C community group Open UI. One of those features is the customizable select, which loves new CSS features — and that love is mutual. A love letter to W3C community groups, new UI capabilities, and CSS, showing how to combine anchor positioning, CSS transitions, scroll snapping, scroll-markers, :has() and much more to create fun, progressively enhanced, customized select elements.
