Yumma CSS is a utility framework built for developers who already think in CSS. Every class name is derived from a CSS property by one rule: the initials of the property, then the initials of the value. d-f is display: flex, jc-sb is justify-content: space-between, mt-4 is margin-top: 1rem. There is no new vocabulary to memorize and no lookup tables, so if you know CSS, you already know Yumma CSS. You still get a full utility workflow on top.
