@Michael:
1. Top fixed menu is fixed menu at the top and it cannot be moved below the logo. So, why don’t you use Primary Menu instead.
2. To increase the font size in the Top Fixed Menu bar, you can edit the font size in the following css and then add it in “Appearance => Theme Options => Custom CSS” box:
#fixed-header-top ul li a {
font-size: 14px;
}
3. You can change the background and color code in the following css as per you need and then add it in “Appearance => Theme Options => Custom CSS” box:
/* Background */
#fixed-header-top {
background-color: #000;
}
/* Text Color */
#fixed-header-top ul.menu > li a {
color: #ddd;
}
/* Text Hover Color */
#fixed-header-top ul.menu li:hover > a,
#fixed-header-top ul.menu ul :hover > a,
#fixed-header-top ul.menu a:focus {
color: #fff;
}
