border-radius: 16px 16px 16px 16px;Overview
Understand what the tool solves, how it works, and the boundaries of its data.
This generator builds one property snippet at a time: border-radius, box-shadow, a two-color linear gradient, or transform. Adjust the controls and inspect the preview, then copy the generated CSS into a stylesheet and adapt the selector to your project.
For example, the radius mode writes four corner values in CSS order; the shadow mode combines horizontal and vertical offsets, blur, spread, color/opacity, and an optional inset keyword. Gradient mode sets an angle plus start and end colors/stops. Transform mode composes translate, rotate, scale, and skew functions. These are property declarations, not a complete component or page stylesheet.
Guide
Follow the workflow and verify inputs and outputs with practical examples.
Choose rounded corners, box shadow, linear gradient, or transform to show the relevant controls.
Set corner radii independently, tune shadow offsets and opacity, choose gradient colors and stops, or combine translation, rotation, scale, and skew.
Look for clipping, contrast, and how the effect changes the sample element. The preview is a useful visual check, not a rendering test in your target page.
Copy the generated line and place it inside an appropriate CSS rule. Add a selector and any surrounding styles yourself.
Use cases
See how the tool fits into real work and everyday tasks.
Adjust each corner separately to find a radius treatment, then copy the declaration into the existing card rule.
Change one control at a time and compare the preview with the generated value to understand which parameter affects the output.
Explore a direction, color pair, or shadow depth before integrating the chosen property into a design system.
Q&A
Find concise answers to common questions and confusing cases.
No. It generates a declaration for one of four CSS effects. You supply the selector, surrounding rule, and any other page styles.
No. The gradient mode generates a linear gradient. The available modes do not include radial gradients, transitions, or animation rules.
The snippet may be applied to a different element or combined with other CSS. Check the target selector, stacking and clipping context, background, and nearby rules in your page.
No. It shows the selected effect in the tool's sample. Test the copied declaration in the browsers and layout that your project supports.
Notes
Review scope, result limitations, and important precautions before use.
Generated values are starting points. A transform can affect an element's visual position without changing the layout space it occupies; shadows may be clipped by surrounding containers, and a gradient or radius may need adjustment for the target element's dimensions. Check contrast, responsiveness, and browser behavior in your actual project.
