SVG color gradient

Quick answer：

SVG color gradient is a technique used in vector graphics to smoothly transition between two or more colors along a path or within a shape. It is defined using the 'linearGradient' or 'radialGradient' elements in SVG (Scalable Vector Graphics). These gradients can be manipulated by specifying color stops at different points along the gradient line or the gradient circle. SVG gradients are widely used in web design for creating visually appealing and interactive elements.
