Ciao, grazie per la risposta.
Sono sempre stato abituato ad usare i cms ed ora mi sto cimendando in realizzazioni "fatte a mano".
Premettendo che tutti gli altri contenuti che ho inserito nelle pagine, dal testo alle foto, vengono riadattate perfettamente, pubblico il css:
codice:
/* Box-sizing -*/
* {
-webkit-box-sizing: border-box;
-moz-box-sizing: border-box;
box-sizing: border-box;
*behavior: url('/test/grid/script/boxsizing.htc');
}
