Design
Color converters, palettes, gradients, contrast checks.
The design tools cover the everyday visual decisions that shape an interface: choosing colors, building palettes, sketching CSS gradients and box shadows, checking accessibility contrast, generating favicons, shaping border radii, designing easing curves, and dialing in modern glassmorphism effects.
Each tool produces ready-to-paste CSS or downloadable assets, and is meant to complement a real design tool (Figma, Sketch) rather than replace it — the small targeted utilities you reach for to grab a specific value or check a single constraint. The WCAG contrast checker, in particular, is the one tool every designer should run before shipping a palette: text that does not meet the contrast ratio is invisible to a meaningful slice of users, and that is a real accessibility violation under modern web regulations rather than a nice-to-have.
