CSS - Syntax to select a class within an id

Question

What is the selector syntax to select a tag within an id via the class name? For example, what do I need to select below in order to make the inner \"li\" turn red?

<         


        

Answer 1

This will also work and you don't need the extra class:

#navigation li li {}

If you have a third level of LI's you may have to reset/override some of the styles they will inherit from the above selector. You can target the third level like so:

#navigation li li li {}
