:point_right: It's always your choice, but you might pick based on what you are styling.

I would expect ems would be handy when you are working with text, and pixels more so when you are working with images or physical devices. Of course, these are very general guidelines, for example: pixels may still be a better choice when styling text if you need to make very accurate adjustments.

Thank you that clears up a lot of misunderstanding on my part from when I was learning about them i did not know when to apply them to what scenarios.
