The tool supports all three standard CSS gradient types: linear-gradient (colors flow in a straight line at a configurable angle), radial-gradient (colors radiate outward from a center point in a circle), and conic-gradient (colors rotate around a center point like a color wheel or pie chart). The generated CSS background property works in all modern browsers.
Yes, you can add as many color stops as you like by clicking the "+ Add Color Stop" button. Each stop has an independent color picker and a position slider from 0% to 100%. Stops are automatically sorted by position when building the gradient, so you can freely rearrange them. There is no upper limit on the number of stops.
