Is it possible to refer to a CSS class inside a different CSS class?

Yes, it is possible to refer to a CSS class inside a different CSS class. This can be achieved by using the class name as a selector for the nested class. For example:

.parent-class .nested-class {
   /* CSS rules for nested class */
}

In this example, the class "nested-class" is nested inside the class "parent-class". The CSS rules specified under this selector will only apply to elements that have both classes.
