A JavaScript library that draws and animates pixel-perfect, typographically optimized text underlines in the browser, with features like descender holes and golden-ratio positioning. It is an exploratory project pushing web typography boundaries and informing a CSS4 proposal to the W3C.
Use cases
- render beautiful animated underlines under text links
- draw underlines that skip around descenders
- achieve pixel-perfect underline rendering on retina displays
- explore advanced web typography effects
- prototype proposed CSS text-underline properties
When to choose
- you want decorative, typographically refined underlines beyond what CSS text-decoration offers
- you're building a design-focused site where link underline aesthetics matter
- you want to demo or experiment with proposed CSS4 underline rules
When to avoid
- you just need standard link underlines - native CSS text-decoration is sufficient
- you need a maintained, production-supported library with a license
- you need broad browser support guarantees or active development
