caption-side: Positioning a <caption> Above or Below a Table
caption-side's only two values (CSS 2.1 §17.4) stack the caption above the row
grid (top, the initial value) or below it (bottom) - always spanning the
table's own content width. The <table> element's own border/background (CSS 2.1
§17.4) wrap the row grid only - the caption sits outside them, in its own unbordered/unfilled area.
