STYLISTIC SETS AND OTHER ASSORTED EFFECTS
Here are a few stylistic sets and other text effects that I've lumped into one final
section. Consider the following examples:
-webkit-font-feature-settings: “ss01” 1, “swsh” 1, “cswh” 1, “calt” 1;
-moz-font-feature-settings: “ss01=1, swsh=1, cswh=1, calt=1”;
-ms-font-feature-settings: “ss01” 1, “swsh” 1, “cswh” 1, “calt” 1;
Explanations of the different declarations used here are as follows:
ss01 . Stylistic sets specify the usage of an alternative set of glyph styles for
the standard glyphs ( Figure 3.25 ).
swsh . Stylistic swashes specify the use of stylistic swashes where available,
which are often similar to stylistic sets, although the latter tend to be more
wide-ranging in terms of the kinds of changes they include ( Figure 3.26 ).
