Right now in my ebook I've got ligatures turned on everywhere with this bit in my CSS...
Code:
-moz-font-feature-settings: "hist=1, liga=1, dlig=1";
-ms-font-feature-settings: "hist", "liga", "dlig";
-webkit-font-feature-settings: "hist", "liga", "dlig";
-o-font-feature-settings: "hist", "liga", "dlig";
font-feature-settings: "hist", "liga", "dlig";
...which works fine, but what would I change that to if I wanted to set up a class to just temporarily turn all ligs off for a word or phrase or something?
