1. Choose the gradient type
Linear gradients transition along a line (horizontal, vertical, or at an angle). Radial gradients radiate from a center point. Conic gradients sweep around a center. Choose based on the visual effect you want.
入力type: linear, angle: 90deg输出linear-gradient(90deg, ...) -
2. Define color stops
Specify two or more color stops. Each stop has a color and optional position (0% to 100% or in px). Without explicit positions, stops are evenly distributed. Add more stops for complex transitions. Use rgba() for transparency.
入力stops: #FF5733, #33FF57, #3357FF输出linear-gradient(90deg, #FF5733, #33FF57, #3357FF) -
3. Generate and use the CSS
The generator produces the CSS background property value. Copy it into your stylesheet. Test in the browser to verify the visual result. Adjust angles, positions, and colors as needed. For repeating gradients, use repeating-linear-gradient().
入力gradient CSS输出background: linear-gradient(90deg, #FF5733, #3357FF);

よくあるエラー
- Gradient not showing
- Apply it to the background or background-image property, not background-color. Ensure the element has dimensions.
- Color stops too close together
- Spread the stops by specifying positions (e.g., 0%, 50%, 100%). Without positions, they are evenly spaced.
トラブルシューティング指引
- If the gradient looks wrong, check the angle and color stop positions.
- For smooth transitions, use colors with similar saturation and lightness.
セキュリティ上の制限
- CSS gradient generation is a design tool with no security implications.
