🎨 OPTIONS 🎨

  • -direction direction — sets the direction of the gradient. If you don't specify it, the system defaults to x, a horizontal gradient. The package supports five directions:
    • x — horizontal gradient (default). Color changes along the x-axis, with the start color at the left. left-to-right slay.
    • y — vertical gradient. Color changes along the y-axis, with the start color at the top.
    • d1 — diagonal gradient from left+top to bottom+right. Color changes along the diagonal, with the start color at left+top.
    • d2 — diagonal gradient from left+bottom to top+right. Color changes along the diagonal, with the start color at left+bottom.
    • r — radial gradient around the center of the viewport. Color changes from the center outward, with the start color at the center.
  • -color1 color — starting color of the gradient. Defaults to red if you don't specify it.
  • -color2 color — ending color of the gradient. Defaults to green if you don't specify it.
  • -type type — how the gradient is calculated. Right now the package supports only one method, which is the default, naturally:
    • linear — linear interpolation between the start and end colors (default).
