Adding extra menus and setting options for them

Hello.
To start, I love the theme. I have tried several that “look” like what I’d want (but really weren’t) and I’ve always come back because of the flexibility of Customizr and the support & documentation provided.

That said, I do need a bit of help…. please. ??
I am using a child theme of Customizr v3.4.20 on WordPress v4.4.2 at https://www.xbydesign.biz.

I have added several menus and managed to get them where I want. If you look at the header, I want the logo centered with the menu items evenly spaced on each side. I have 2 problems:

1) Responsiveness – As of now, I have done this with positioning for all header items (menu, logo, tagline, socials). However, I’d like to do it in a way that it is still responsive.

2) Sticky menu – I’d like to have the menu to be sticky. Right now I have a placeholder (empty) menu as the main menu because I only see that the main menu can be sticky. Prior to using the “placeholder” menu I managed to do this with the following bit of code but it also hid the tagline & socials (trouble isolating just the main menu):

.sticky-enabled .tc-header .navbar .navbar-inner {
    display: block;
}
.sticky-disabled .tc-header .navbar .navbar-inner {
    display: none;
}

If I could just accomplish these 2 things I would be a happy camper. Any suggestions?
