+<p>The <span title="font-variant!!property">'font-variant'</span> property
+is a shorthand for all font-variant subproperties.
+The value <dfn id="font-variant-normal-value" title="normal!!font-variant">'normal'</dfn>
+resets all subproperties of <span title="font-variant!!property">'font-variant'</span>
+to their inital value.
+The <dfn id="font-variant-none-value" title="none!!font-variant">'none'</dfn> value
+sets 'font-variant-ligatures' to 'none'
+and resets all other font feature properties to their initial value.
+Like other shorthands,
+using <span title="font-variant!!property">'font-variant'</span>
+resets unspecified <span title="font-variant!!property">'font-variant'</span> subproperties
+to their initial values.</p>
+
+<p>It does not reset the values of
+'font-language-override',
+<span title="font-feature-settings!!property">'font-feature-settings!!property'</span>
+or <span title="font-variation-settings!!property">'font-variation-settings!!property'</span>.</p>
