Compose CSS is a personal investigation and tools-building effort. I´m trying to find out for myself what is useful to have in a CSS library and how that lib should be structured. ulf.codes is created by using Compose CSS. Compose CSS will probably change drastically and often until I find something that´s working for me.
I´m inspired by Heritage of Kumiko Crafts. You can watch there how the craftsmen have created their own very specific tools for very specific jobs – which is what I´m aiming to do with Compose CSS for my web development.
