CSS & Design

CSS visual properties like box shadows, border radii, and gradients are powerful but tedious to write by hand. The CSS & Design category offers four focused tools that let you design these properties visually and copy production-ready CSS code instantly. No guessing at values or toggling browser DevTools — just drag a slider and copy the output.

The CSS Box Shadow Generator supports multiple stacked shadow layers with full control over offset, blur, spread, opacity, and colour. The CSS Border Radius Generator handles all four corners independently, including elliptical values for creating organic blob shapes. The Gradient Generator produces linear, radial, and conic CSS gradients with multiple colour stops and a live preview panel.

For spacing and layout work, the Aspect Ratio Calculator computes missing dimensions and simplifies ratios for responsive images and video embeds. The Pixel to REM Converter (also in Unit Converters) bridges the gap between fixed pixel designs and accessible, scalable rem-based CSS. These tools are indispensable for front-end developers and UI designers who value precision and speed.
