<div style="clear:left; padding-bottom:100px;"></div>

Questo è il codice css

#men_sx{
padding-top:3px;
text-align:left;
float:left;
width:160px; /* 162 */
border:#333333 1px solid;
}

#men_dx{
padding-top:3px;
float:left;
width:168px; /* 170 */
border:#333333 1px solid;
}

#men_centro{
padding-top:3px;
float:left;
width:530px; /* 532 */
text-align:left;
padding-left:2px;
border:#333333 1px solid;
}
