Frames and Triangles, Part 2

Now you need to perform the following to create a triangle:

  • Set one border of the frame to zero width,
  • make two more borders transparent,
  • and then assign the desired color to the last border.

Thus, by using a typical border, you can create triangular arrows pointing in all directions.

Let’s create a triangular arrow pointing down.
