Plugin no responsive?

Hi!

It looks like the container does not respond as it should. In these cases I usually suggest a custom CSS to force a certain width on the elements on different screen sizes, something like this:

@media only screen and (max-width: 768px) {
    .rpp_item {
        width: 33% !important;
    }
}

@media only screen and (max-width: 600px) {
    .rpp_item {
        width: 50% !important;
    }
}

@media only screen and (max-width: 380px) {
    .rpp_item {
        width: 100% !important;
    }
}
