I've created a pen: https://codepen.io/nickelse/pen/dROOGX
On the 2nd div I want the close button to the slide the parent div back up again, I can't figure out why it's not working, any suggestions?
$(".one").click(function(e) {
    e.preventDefault();
    e.stopPropagation();
    // do your worst, i.e. slide down
    $(".two").slideDown("slow");
});
$(".close").click(function() {
    // slide up
    $(".two").slideUp("slow");
});.container {
    overflow:hidden;
    height: 60px;
}
.one {
    position: relative;
    top: 0;
    background-color: lightblue;
    z-index: 1;
}
.two {
    position: relative;
    background-color: yellow;
    z-index: -1;
    display:none;
}
/*
.one:hover + .two {
    top: 0px;
}*/
.red-cell {background: red!important;}
.close {background: red; display:block;}<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.1.1/jquery.min.js"></script>
