Convert web colors across HEX (#3b82f6), RGB (rgb(59, 130, 246)), and HSL formats with interactive color preview and 1-click CSS copying.
Choosing the right color format in CSS affects maintainability. HEX codes are compact, but RGB and HSL offer alpha transparency support (RGBA and HSLA).
This utility converts HEX codes to rgb(), rgba(), and hsl() notations with instant preview swatches.
HSL (Hue, Saturation, Lightness) makes it effortless to create cohesive color palettes, hover states, and dark mode variants by adjusting only the lightness percentage.
Convert PX to REM and REM to PX in real-time with customizable base font size (16px default) and comprehensive typography reference tables.
Generate fluid, responsive font sizes and spacing that scale smoothly across mobile and desktop screens without media query breakpoints.
Calculate matching dimensions, aspect ratio fractions, and CSS aspect-ratio properties with instant presets for popular device resolutions.
Design multi-layered CSS box shadows visually with real-time preview, opacity sliders, blur spread controls, and 1-click CSS code export.
