FAQ

A: Copy the CSS code into your stylesheet, then add the class name from the sample HTML to the element where you want the gradient to appear.

A: Linear gradients are suitable for page backgrounds and banners; radial gradients are ideal for spotlight and soft diffusion effects; conic gradients work well for borders, badges, and visuals with a sense of rotation.

A: You can increase the background size, add more colors, adjust the color stops, or choose animation styles such as diagonal flow or breathing flow.

A: Yes. Select “Gradient Text” as the output purpose, and the tool will generate CSS code containing background-clip:text.
