+RFS can ben enabled or disabled with a class. There are 3 options:  
+- `disable`  
+When the the disable classes are generated you can add the `.disable-responsive-font-size` class to an element to disable responsive font sizes for the element and its child elements.  
+- `enable`  
+RFS is disabled by default in this case. The `.enable-responsive-font-size` class can be added to an element to enable responsive font sizes for the element and its child elements.  
+- `false`  
+No extra classes are generated.  
 
-When the the disable classes are generated you can add the `.disable-responsive-font-size` class to an element to disable responsive font sizes for the element and its child elements. If you don't use this, it's better to set this to `false` to prevent the generation of unused css. This doesn't apply on font-sizes which are inherited from parents.
