.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; 
}
