On the next line, use jQuery to select all list items (li) in an unordered list (ul) with the class of 'nav'?

$(".nav ul li");

Not sure what is wrong here?

I believe ...

.nav ul would be:

<div class="nav">
    <ul>
        <li></li>
    </ul>
</div>

and ul.nav would be:

<ul class="nav">
    <li></li>
</ul>

so "use jQuery to select all list items (li) in an unordered list (ul) with the class of 'nav'?" will be:

$("ul.nav li");

$(".nav ul li");

the above can be translated as "li inside ul that is inside class of 'nav'."

ul with the class of nav should look something like this:

$("ul.nav");

"li inside ul that is inside class of 'nav'" -- is that the same thing as ALL li inside ul, or only ONE li inside ul?

Also, what exactly is the difference in html between ul.nav and .nav ul?

<!code> <div class="nav"> <ul> </ul> </div>

VS. ''' <div class="nav ul"></div> '''
