Font SIze and Spacing of Drop down Menu

I figured out how to change the font size and spacing on mega menu from one of the other posts. However, I have one main menu item that is just a drop down. Can you provide the css for the drop down to match my existing font size and spacing like i have it in my mega menu please. Below is what i currently have in my css:

.logo img { position: relative; top: 6px; }
#top #header .av-main-nav > li > a {
        font-size: 20px !important;
    }
}
#top #header .avia_mega_div > .sub-menu > li > ul > li a { padding-top: 0; }
.avia_mega_div .avia-bullet { margin-top: 8px; }
#top #header .avia_mega_div > .sub-menu { padding: 5px 18px 5px; }
#top #header .avia_mega_div > .sub-menu > li > ul > li a { font-size: 14px; }
#top #header .mega_menu_title a { font-size: 16px; }
.av-main-nav > li > a {
    padding: 0 20px;
}

.av_seperator_small_border .av-main-nav > li > a > .avia-menu-text{
    padding-left: 20px;
    margin-left: -20px;
}
