I just want to know what the * selector is doing. I looked up what the box-sizing is and have loose idea of what that is doing, but I don’t get why I needed to use *. That doesn’t seem to be referencing anything in the code. I’ve finished this lesson and nowhere do I ever even use another *. Is it a sort of select all selector. Like, does using a * mean that the following code is applied to everything? Why not set the selector to img, div, or body?
Your code so far
