Heyah,
I made a burger menu icon, and I want it to change color when you hover over it, but somehow it doesn't work and I don't understand why. I have those 3 spans, which when the menu is clicked turn into just two, and I got the hover effect to work for each span inividually, but I want all spans to change color at a time.
$(document).ready(function(){
    $("#burger-container").on('click', function(){
        $(this).toggleClass("open");
    });
});#burger-container{
    margin: 25px 0 0 0;
    width: 50px;
    float: right;
    padding-right: 70px;
}
#burger{
    cursor: pointer;
    display: block;
    width: 50px;
    height: 50px;
}
#burger span{
    background: black;
    display: block;
    width: 50px;
    height: 3px;
    margin-bottom: 10px;
    position: relative;
    top: 0;
    transition: all ease-in-out 0.4s;
}
#burger-container.open span:nth-child(2){
    width: 0;
    opacity: 0;
}
#burger-container.open span:nth-child(3){
    transform: rotate(45deg);
    top: -13px;
}
#burger-container.open span:nth-child(1){
    transform: rotate(-45deg);
    top: 13px;
}
span.hover:hover{
   background: #666666;
