I've got a page full of cards that I'd like to divide into two columns. So far so good, but in Firefox/Win, the heights of the two columns are way different — there's a big gap at the bottom of the first column while the other goes on and on...
Here's the relevant CSS for the enclosing div:
column-count: 2;
column-gap: 0.8em;
column-fill: balance;
I'd be very grateful of any help sorting this out.
