}

.conic-gradient {
  background-image: conic-gradient(yellowgreen 40%, gold 0deg 75%, #f06 0deg);
}

/* becomes */

.linear-gradient {
  background-image: linear-gradient(90deg, black 25%, black 50%, blue 50%, blue 75%);
  background-image: linear-gradient(90deg, black 25% 50%, blue 50% 75%);

should be preserved. By default, double-position gradients are preserved.

postcssDoublePositionGradients({ preserve: false })
```

```css
.linear-gradient {
  background-image: linear-gradient(90deg, black 25% 50%, blue 50% 75%);
}

.conic-gradient {
  background-image: conic-gradient(yellowgreen 40%, gold 0deg 75%, #f06 0deg);
}

/* becomes */

.linear-gradient {
  background-image: linear-gradient(90deg, black 25%, black 50%, blue 50%, blue 75%);
}

.conic-gradient {
  background-image: conic-gradient(yellowgreen 40%, gold 0deg, gold 75%, #f06 0deg);
