<style type="text/css">
body > div
{
column-gap: 1em;
font: 1.25em/1 Ahem;
width: 41em;
}
/*
N == 3;
W == max(0, (available-width - ((N - 1) * column-gap)) / N);
W == max(0, (41em - ((3 - 1) * 1em)) / 3);
W == max(0, (41em - (2 * 1em)) / 3);
W == max(0, (41em - 2em) / 3);
W == max(0, 39em / 3);
W == max(0, 13em);
W == 13em;
The height of column rule depends on number of line boxes in
each outer column box which depends on number of line boxes
in each inner column box. So:
13em : width of each outer column box
-
2em : horizontal margin of each div inside
=======
11em : width of each inner multi-column elements
N == 3;
W == max(0, (available-width - ((N - 1) * column-gap)) / N);
W == max(0, (11em - ((3 - 1) * 1em)) / 3);
W == max(0, (11em - (2 * 1em)) / 3);
W == max(0, (11em - 2em) / 3);
W == max(0, 9em / 3);
W == max(0, 3em);
W == 3em;
So, each duo of 'a', 'm' and 'x' should fill one and only 1 line
box. There are 8 duos; therefore, the first 2 inner
column boxes should use 3 line boxes and the 3rd inner
column box should be using 2 line boxes.
So, the height of the 2 blue column rules should be 60px.
