I have a simple SVG graphic with a path for a mask. As soon as I assign the #myMask to the object,the mask doesn't work at all. This should be something obvious, but I'm not seeing it.

Thoughts?

CodePudding user response：

I think that there was something about the position of the elements. And then your mask more or less covers the entire arrow. I cleaned up a bit and positioned your elements in the viewBox of "0 0 500 500", so that there is no need for using transform/translate.
