   Středový dialog: hairline rámeček, velký nadpis, pole jen s podtržením, patička oddělená linkou.
   Na mobilu spodní list. Formuláře (.bs-modal, .bm-drawer) i krátké dialogy (.bm-dialog) vypadají stejně.
   Chipy: A = mřížka stejných buněk pro krátké výběry, D = pole s popoverem (.bm-multi).
   Pravidla: jedna vrstva (z-index 10000, nad plovoucími widgety), zatemnění rgba(20,19,15,.5) + blur,
   hlavička pevná, vybraný stav nikdy nemění rozměr. */
