 You can combine the ID selector with other types of selectors to style a very specific element.
 ```css
-section#about:hover { color: blue; }
+section#about:hover { color: blue; } /* applies style to hover state of section element with an ID of 'about' */
 
-div.classname#specified_id { color: green; }
+div.classname#specified_id { color: green; } /* applies style to a div element with a class name of 'classname' and an ID of 'specified_id' */
