	6 The specified, computed, and used value of column-count is 2, but the

	7 actual column-count will be larger, because the column height is only 40px,

	8 and we have 200px of content. So we'll get ceil(200/40) = 5 columns.

	9

	10 Used / actual column-width becomes 0, because the gap eats everything.

	11

	12 So we get:

	13 Column 0: +0px = 0px

	14 Gap between column 0 and 1: +200px = 200px

	15 Column 1: +0px = 200px

	16 Gap between column 1 and 2: +200px = 400px

	17 Column 2: +0px = 400px

	18 Gap between column 2 and 3: +200px = 600px

	19 Column 3: +0px = 600px

	20 Gap between column 3 and 4: +200px = 800px

	21 Column 4: +0px = 800px

	22 -->
