Working in Design & CSS
Design engineers live between two worlds: the visual intent of a designer and the mathematical reality of CSS. ASG Tools' design category builds the bridges. The fluid clamp() calculator turns a design spec — a minimum size, a maximum size and two viewport breakpoints — into a production-ready CSS clamp() formula with the interpolation math done for you. The contrast inspector computes WCAG 2.1 relative-luminance ratios for any color pair and tells you, pass or fail, exactly which accessibility tiers your combination reaches.
Both tools share the same philosophy: show the math, not just the answer. The clamp calculator exposes the slope and intercept it derived, so you can sanity-check the curve and tweak the breakpoints with full understanding. The contrast inspector renders a live preview of your foreground/background pair at normal and large text sizes, so accessibility becomes something you see rather than a number you trust blindly.
Because everything executes client-side, you can drop in brand colors from unreleased design systems without leaking a launch. Paste hex values from Figma, experiment freely, and copy the resulting CSS with one click. Future batches in this category will add gradient generators, fluid spacing scales and design-token converters.
