millenium-bug

github.io·Infrastructure

millenium-bug is a lightweight, dependency-free CSS library that transforms semantic HTML into interfaces resembling late-1990s banking and enterprise software. It provides styles for windows, tabs, forms, tables, modals, and more using a classless-first approach with optional .mb-* modifiers. Ideal for rapid prototyping of CRMs, admin panels, or adding nostalgic "certified in 1999" aesthetics to projects.
