Sumi.css

Sumi.css is a CSS framework that styles plain, semantic HTML so a page looks finished without adding classes; this “classless-first” approach means headings, forms, tables, cards, accordions, modals and navigation are styled from the HTML element alone. ^[1a][1b] It also offers optional classes and attributes for layout, typography, buttons, validation states, tooltips, themes and other specific effects. ^[2] For example, a page using ordinary HTML elements such as nav, form, table, article, details and dialog gets styled navigation, fields, tables, cards, accordions and modals from those elements alone. ^[3a][3b]
