What we are specifying here is grid template with auto 1FR for this middle space and then auto for the footer. And then we've got our columns of auto 1FR and auto. So you get the Holy Grail layout. This is not exactly one line. I mean, all of these, you know, you have a little bit more to add. You can then specify grid columns and rows.
