.control.my-control {
    overflow: hidden;
    display: block;
    border: 1px solid black;
    margin: 15px;
    width: 300px;    
}

.control.my-control > div {
    float: left;    
}

.control.my-control > div + div {
    float: right;
    border-left: 1px solid black;    
}

.control.my-control > div + div > img {
    height: 50px;
}

.control.my-control > div > div {
    padding-left: 3px;
    padding-top: 3px;
}

.control.my-control > div > div > div {
    float: left;
}

.control.my-control > div > div > div:last-child {
    float: none;
    clear: both;
}

.control.my-control > div > div > div + div {
    padding-left: 12px;
}

.control.my-control > div > div + div > div + div {
    padding-left: 3px;
}

.control.my-control > div > div > div > div.lyric-content {
    overflow: hidden;
    width: 180px;
    white-space: nowrap;
}
