Challenge: Descendants of Khan

 is a programming challenge in the HTML/CSS: Making webpages course. This challenge practices grouping CSS selectors.

Steps
There are two step in this challenge:
 * 1) Add a rule for emperor classes in the table: This step asks users to use descendant selectors to add a rule that targets only the elements that have the emperor class and are in the table.
 * 2) Add a rule for reign classes in the table: This step asks users to use descendant selectors to add a rule that targets only the elements that have the reign class and are in the table.

If users get stuck
If users get stuck, they should:
 * Pay attention to Oh Noes and the error messages.
 * Go back to the "More CSS selectors" tutorial.
