UI

Top Border Stays When Scrolled

Notes

Adjusting border the way we did, in the thead, may create an issue. It allows the body to ever so slightly be seen behind the thead. Possible fix is making top: -1px. Any other ideas welcomed.

Answer: This was not just a me thing.

I mislead you yesterday. I'm gonna try to do this one, because I'm having trouble making sure nothing unexpectedly breaks.
