Free Design & CSS Tools — Colors, Gradients and Effects, Visually
CSS can describe beautiful things, but nobody designs by typing numbers blind. These tools put a live preview between you and the code: drag sliders, pick colors, watch the result, then copy CSS that is ready to paste into your stylesheet.
Color work starts with the Color Converter, which keeps HEX, RGB and HSL in sync as you type — with HSL being the format that makes lightness and hue adjustments intuitive. Build complete schemes with the Palette Generator, which applies real color theory (complementary, analogous, triadic and more) to any base color and exports CSS variables. Then verify readability with the Contrast Checker, which grades any text/background pair against the WCAG accessibility thresholds that audits and regulations use.
For surface styling, the Gradient Generator designs linear, radial and conic gradients with up to three stops; the Box Shadow Generator crafts elevation effects from subtle cards to dramatic floats; and the Border Radius Generator handles everything from consistent corner rounding to organic blob shapes using the eight-value syntax.
Designers use these tools to explore ideas quickly; developers use them to translate design intent into exact CSS without guesswork. Either way, the feedback loop is instant.
