change menu box color

Try this:

/*  Adjust Navbar Box settings      */
 .navbar.notresp .navbar-inner  {
background-color:   #ba0000;                   /* Change #ba0000 */
background-image:   linear-gradient(to bottom, #ba0000, #ba0000);      /* Change #ba0000, #ba0000 */
background-image:   -webkit-linear-gradient (top, #ba0000, #ba0000);   /* Change #ba0000, #ba0000 */
background-repeat:  repeat-x;
border:             1px solid #ba0000;         /* Change [1]px, #ba0000 */
}

This will give you solid #ba0000, but you might want to experiment with the gradients.

You realize you are posting in the support forum for the Customizr theme?

You might have better luck in your theme’s support forum, here.

Okay…sorry…no problem…

So, in answer…you can use an image as the background of the navbar too…

Well…I see you are back to your Quark theme…just for future reference, if you want targeted support, you will want the Customizr theme running…

So…it would be similar to what you did for your body background, just with a different selector, something like this:

.navbar.notresp .navbar-inner {
background: url(/wp-content/uploads/YOUR_FILE.png) repeat;
}

the first four lines of properties in the code rdellconsulting gave you would not be needed…you may want to keep the border…
