 As described in the previous section,
 font features and variations can be enabled in a variety of ways,
 either via the use of 'font-variant!!property',
-'font-feature-settings!!property',
-'font''font-variation-settings!!property' in a style rule
+'font-feature-settings!!property', or
+'font-variation-settings!!property' in a style rule
 or within an ''@font-face'' rule.
 The resolution order for the union of these settings is defined below.
 Features defined via CSS properties are applied on top of layout engine default features.
