Smaller Menu size

Hey there!
I would like to shift the top navigation down closer to the bottom of the container. Could you send along the css?

Thanks, tho I did try that and nothing happens. I do not see a conflict, but here is what I have in the quick css so far:

.header_color .container_wrap_meta {
background: #a81010;
}
.header_color .phone-info, .header_color .phone-info a, .header_color .av-sort-by-term a {
color: #FFF;
}
.header_color .social_bookmarks a {
color: #FFF;
}
.rpwe-block h3 {
background: none!important;
clear: none;
margin-bottom: 0!important;
margin-top: 0!important;
font-weight: bold;
font-size: 12px!important;
line-height: 1.5em;
color: #a81010;
}
.whitequote {
size:20px;
line-height: 1.5em;
}
.entry-content-wrapper li {
margin-left: 0;
}
#socialmedia-container {
padding-left: 0px;
}
#avia-menu > li > a {
font-family: ‘Open Sans’;
font-size: 16px !important;
color: #444444 !important;
}
#avia-menu > li > a:hover{
color: #a81010 !important;
background: #e1e1e1;
}

#avia-menu .sub-menu a{
font-family: ‘Open Sans’;
font-size: 15px;
color: #a81010;
background-color: #fff;
}

#avia-menu .sub-menu a:hover{
color: #cc4400;
text-decoration: underline;
}
#header_main .container, .main_menu ul:first-child > li a {
line-height: 300px;
}

Excellent, that works! Thanks again. BTW do you know how I could replace that whole top nav which we just moved down with a tagline (i.e., NO menu there, just text)?
