Solution

add 50px on your lb-outerContainer class and also on your lb-dataContainer class

.lb-outerContainer {
   position: relative;
    background-color: white;
    width: 250px;
    height: 250px;
    margin: 0 auto;
    -webkit-border-radius: 4px;
    -moz-border-radius: 4px;
    -ms-border-radius: 4px;
    -o-border-radius: 4px;
    border-radius: 4px;
    /* top: 50px; */
    top: 50px;
}
.lb-outerContainer{
    margin: 0 auto;
    padding-top: 5px;
    top: 50px;
    position: relative;
    width: 100%;
    -moz-border-radius-bottomleft: 4px;
    -webkit-border-bottom-left-radius: 4px;
    border-bottom-left-radius: 4px;
    -moz-border-radius-bottomright: 4px;
    -webkit-border-bottom-right-radius: 4px;
    border-bottom-right-radius: 4px;
}
