It's the short way of writing linear-gradient(currentColor,currentColor). The direction and the color stops aren't important since a gradient between two same colors will always give that color. I am defining two colors stop for it (0 and 0) to write the color only once inside the gradient.
The syntax I am using is a bit uncommon but it's valid. The CSS validator is never up to date anyway.

Cool, didn’t know that syntax!
