Fill Gradient Stops
fill-gradient-stops
The fill-gradient-stops parameter sets where each color of a fill-gradient-linear or fill-gradient-radial list sits along the gradient. Without it, the colors are spaced evenly.
Pass one position per color, from 0 (the start of the gradient) to 100 (its end), separated by commas. Positions must never decrease. Two neighbors at the same position produce a hard edge instead of a blend, which is how you build a flag or a banded background.
A list whose length does not match the color count, whose positions decrease, or whose values fall outside 0–100 is ignored, and the colors are spaced evenly instead.
Repeating a position gives a hard split.
