CSS Function Recipes is an interactive playground for front-end developers exploring native CSS custom functions. Use eight hands-on examples to tune parameters, edit live CSS, and see how @function can replace repeated declarations or JavaScript-generated values.
Features
- Eight practical recipes cover color mapping, interface density, motion, transforms, shadows, gradients, easing, and fluid scales.
- Live parameter controls update each preview and result summary as values change.
- Editable CSS inputs keep the preview and source code synchronized while you experiment.
- Implementation comparisons show the repeated CSS or JavaScript logic each custom function can replace.
- Copy-ready output combines the function, properties, inputs, and call sites into a reusable snippet.
How it works
- Choose a recipe — open an experiment from the index to explore the technique in context.
- Tune the inputs — adjust the controls or edit CSS values and watch the preview respond.
- Review the result — connect the visual outcome to the values produced by the function.
- Inspect the code — examine the function definition, its call sites, and any required property setup.
- Reuse the pattern — copy the live CSS and adapt the variables to your own inter
