Tune a card shadow using offsets, blur, spread and a colour.
A practical starting example
A soft card shadow using offsets, blur and spread.
Tune a card shadow using offsets, blur, spread and a colour.
Use this as a small trial before applying the operation to your real input. A sample illustrates the workflow; it does not promise a specific result for every source file or device.
How to use CSS card shadow
- Paste your text or use the example to inspect the operation.
- Review the options before running: Horizontal offset: 0 · Vertical offset: 12 · Blur radius: 28 · Spread: 0 · Shadow colour: #102937
- Inspect the preview or result. Use the application’s copy or download option when it is available.
Prepare the input
Use the controls described in the application.
Review the available controls
| Control | Starting value | Review before processing |
|---|---|---|
| Horizontal offset | 0 | Check this against your intended css card shadow result. |
| Vertical offset | 12 | Check this against your intended css card shadow result. |
| Blur radius | 28 | Check this against your intended css card shadow result. |
| Spread | 0 | Check this against your intended css card shadow result. |
| Shadow colour | #102937 | Check this against your intended css card shadow result. |
How to decide whether the result is useful
Compare the preview against your real page background. A shadow can be invisible on a dark surface or misleadingly heavy when the component is small.
- Compare the output with the unchanged source.
- Check the destination requirement before copying, downloading or uploading it.
- Review meaningful values and characters; a successful operation does not validate every downstream use.
- Use a second representative sample if the first does not cover the difficult part of your input.
Limitations and troubleshooting
Review the output before using it. Your original input is not changed.
If the output does not match your intention
Return to the original copy, review the selected input and controls, and repeat with a smaller sample. If the embedded view is unavailable, use the direct tool link at the top of this page. Browser support and device memory can affect file-based workflows.
Questions about this tool
Does copying the shadow include the entire card design?
No. It supplies the box-shadow declaration. Spacing, borders and typography still come from your CSS.
Can I use the tool from this guide?
The main button opens the working tool on its Tabaix subdomain. An optional embedded view may be added to this guide; the direct link remains available for larger screens, downloads or browser compatibility.
What should I keep before changing the input?
Keep an unchanged source and record any controls you chose. That gives you a comparison point and lets you repeat the task without replacing your original.
