CSS menu highlighting not staying on child hover

Question

I am trying to create a layered menu with css. My problem as you can see, is that when I go to the 3rd UL, that the second UL loses its styling (white font color). What am I missing in my css to keep the second UL at a white font with the light blue BG like I did with the top UL?

<nav id="menu">
<ul>
    <li><a>Users</a></li>
    <li>
        <a>Applications</a>
        <ul>
            <li>
                <a>Application 1</a>
                <ul>
                    <li><a>Users</a></li>
                    <li><a>Roles</a></li>
                    <li><a>Groups</a></li>
                </ul>
            </li>
        </ul>

Answer 1

You can just change line 75 in the CSS of that Pen to nav ul li:hover > a - The link overrides the color of the text, that's why you'd need to over-specify this rule.
