Build CSS from shadow offsets, blur, spread and color.
How this tool works
Horizontal and vertical offsets position the shadow; blur softens it and spread grows or shrinks its extent. The generated declaration uses a validated HEX color. Try subtle values for cards and stronger ones for overlay elevation.
Use it in three steps
- Open the workspace and enter horizontal offset. The sample provides a safe starting point with no personal data.
- Adjust the visible settings, then run the utility. Validation errors explain which input needs attention.
- Check the output against your task. Copy the text or download the generated file when you are satisfied.

Run the utility, inspect the result and change one value to see how the output responds. Your source input remains available so you can compare it with the result before copying.
Example output from the bundled engine
box-shadow: 0px 8px 24px -6px #a18bcc;
Your result depends on the supplied input and settings. Compare it with your original before using it.
Limits and responsible use
Blur must be non-negative. Strong shadows do not replace visible focus indicators.
Privacy and output
Processing takes place in this browser workspace. The tool does not call a model API or upload the supplied text or image. Results are temporary until you copy or download them; reloading the page clears the working session. Website account and contact forms are separate from the utility and are explained in our Privacy Policy.
