Buongiorno,

mi affido a questo forum chiedondo il seguente aiuto:
vorrei sovrapporre perfettamente il tag <hr> al border-bottom del div colonnaCentro.
Con il seguente codice CSS funziona con firefox ma non funge con IE7.
Per la creazione del sito sto utilizzando Dreamweaver CS4
Aiutatemi per favore!
