zephyr is a tailwind-inspired css generator dsl. it acts as a replacement for inline styles, with the added ability of pseudo-elements, pseudo-classes, and more
so far the only documentation is on the github readme
it's still unpolished, but i've been using it on production systems for a while and it's been nice :)
this website itself uses zephyr. you can read the generated css here
this is a playground, which allows you write some html and see the generated css out of the parsed classes
try adding class="bg[black]" on the body tag
