So, if for example, we wanted to change the colours for a book themed template, someone would have to add:

.portable-infobox-theme-book {
    background-color:#000 !important;
}
.portable-infobox-theme-book .item-type-key-val:not(:last-of-type), .portable-infobox-theme-book .item-type-group {
    border-bottom: 1px solid #445;

to the CSS?
