theres no background-color in the "selected' class???

in the first line where we declare the variable 'color', we are taking the background-color from the selected class but in the css it looks like this:

.selected {
    border: 7px solid #fff;
    width: 40px;
    height: 40px;

see theres no background-color so i dont really understand

Hey Kevin,

You're talking about this line?

var color = $(".selected").css("background-color");

If so, all it does is grab any element that has a class of selected and get that element's background-color. So here,

<ul>
    <li class="red selected"></li>
    <li class="blue"></li>
    <li class="yellow"></li>
</ul>

It grabs the background color of that li element that has the class of selected and stores it in the variable color.
