A title at the top of a column of text can appear to be lower than the top line of text on the opposite page or in the adjacent column because of the half-leading(1) that is ordinarily added above and below the text of every line. The half-leading on the first line of body text is usually not obvious, but half-leading can be noticeable when large text, with larger half-leading, is opposite smaller text. Half-leading on the first line in a column is discarded when line-height-conditionality: discard; is specified. Specifying a common -ah-baseline-grid keeps the text after the heading aligned with lines in the adjacent column or opposite page, irrespective of the line height of the initial title.
