トラブルシューティング

Gradient appears as a solid color instead of a transition

解決策

Ensure at least two distinct color stops are defined. If both stops are the same color, the gradient will appear as a solid fill. Add a second color stop with a different color value.

Gradient direction is not what I expected

解決策

CSS gradient angles start at 0° (bottom to top) and increase clockwise. 90° goes left to right, 180° goes top to bottom, and 270° goes right to left. Adjust the angle accordingly.

Generated CSS does not work in my browser

解決策

Linear gradients using standard CSS syntax are supported in all modern browsers. If you need IE11 support, add a vendor-prefixed fallback: -webkit-linear-gradient().

よくある質問

What types of gradients are supported?

Linear gradients with custom direction and multiple color stops are fully supported. Radial gradients and conic gradients may be added in a future update.

How do I create a transparent gradient?

Add a color stop using RGBA or HSLA with an alpha value of 0 for full transparency. For example, use rgba(0,0,0,0) as one stop and rgba(0,0,0,1) as another to fade from transparent to solid black.

Can I create a gradient that repeats?

The generator creates standard linear-gradient(). For repeating patterns, change the CSS property name to repeating-linear-gradient() in your stylesheet after copying the generated code.

What is the difference between background-color and background when using gradients?

CSS gradients are images, not colors, so they must be applied using the background or background-image property, not background-color. Using background is the most concise approach.

Can I use this gradient for text?

Yes. Apply the generated CSS to the text element, then add: -webkit-background-clip: text; background-clip: text; color: transparent; to clip the gradient to the text characters.

How many color stops can I add?

CSS gradients support unlimited color stops. For usability, keeping gradients to 2–4 stops is recommended. Very complex gradients with many stops can be hard to reproduce or adjust later.

Is my data sent to a server?

No. Gradient generation happens entirely in your browser. No data is transmitted or stored.

Can I export the gradient as an image?

The tool generates CSS code. To export the gradient as an image, take a screenshot of the preview panel or use a canvas-based tool to render and download the gradient as a PNG.
