How this tool computes its result
Builds either a linear-gradient(angle, stops) or radial-gradient(circle at center, stops) CSS value from 2 or 3 independently positioned color stops, each with its own 0-100% slider. The angle slider (0-360deg) is disabled whenever the radial type is selected, since radial gradients here are fixed to 'circle at center' with no configurable shape or position. Stops are concatenated in the fixed order A, B, (optional C) exactly as entered — the code never sorts them by percentage.
