Background does not resize in height

Hello,

Your plugin does not seem to be responsive in my theme (Voice).

I had to add these css rules:

.rcc-panel {
    height: 70px;
}

@media only screen and (max-width: 1023px) {
.rcc-panel {
    height: 90px;
}
 }

@media screen and (max-width: 782px) {
.rcc-panel {
    height: 115px;
}

.admin-bar {
    padding-top: 0;
}
}

@media only screen and (max-width: 670px) and (min-width: 200px) {
.rcc-panel {
    height: 150px;
}
}
