The transitionals are also paired with the humanists. The slab serifs are paired with the grotesques, and some variants of the slab serifs are also said to match the geometrics or humanists. 3.2 Ligatures, Small caps fonts and expert fonts Ligatures Properly spacing fonts brings with it all sorts of issues. The problem is that this causes the dot on the i to collide with the f, and the serif on the head of the i to collide with the horizontal stroke of the f. To deal with this problem, font collections include ligatures.
Most fonts contain fi and fl ligatures.
Expert fonts discussed later often include extra ligatures, such as ffl, ffi, and a dotless i character. Small caps fonts are fonts that have reduced size upper case letters in place of the lower case letters. Expert fonts consist of several extras designed to supplement a typeface. 3.3 Font Metrics and Shapes Font metrics define the spacing between variable width fonts. In addition to the metrics, is the font outline, or shape.
