When I first learned anchor positioning, I built a demo to help me figure out how it all worked. The inline-end tells me that one of those columns is the inline-end . Do we start all the way on the left and spanning three columns, or are we starting in the center and spanning just the two? Looking at this property, there’s no way to tell. I’m wondering if there should be a change to how CSS works, so that, instead, developers would write center-span-inline-end .
