Making a Real-Time Clock With a Conic Gradient Face

In this second part of my customizable select series, I’d like to highlight one feature from Interop 2025 that works beautifully with this feature: anchor positioning. This article contains one of my first demos ever created when styling the select and has evolved with every new syntax and iteration across the months / years. We'll also be taking a glimpse at a few experimental features, but the basis of this can be used today. Let’s take a look at my potion selector with CSS.

The customizable select has entered Chrome 134, allowing us to style this form element to our hearts' content. I decided to write a series about this feature because there are so many cool things we can do with CSS these days to create some really unique and fun experiences. In this first article of the series, I want to talk a bit about the history, while also giving an in-depth guide on how you can start creating your first customizable select as a progressive enhancement, today.
