Drop down menu for folder is solid white (unreadable)

I added something to the CSS to allow my header to be fixed and the colors to blend.  I think in doing so I've created an issue with a main nav folder and its dropdown menu.  See attached screen shot for how it's simply appearing white with no navigation showing.  I have my site on private and password protected, so let me know if I can also screen shot the CSS code injections I've added.  

Thanks!

span.Header-nav-folder {
    background-color: #005285 !important;
}
span.Header-nav-folder * {
    color: white !important;
}

This worked, as always.  Thank you, @tuanphan 
I'm buying you a coffee : )

@tuanphan I would appreciate all of this help from you.  I'm so grateful.  

I'm having this exact same problem. I tried adding in the recommended code but it didn't change anything for me.  My site URL is below. If anyone has any suggestions, it would be greatly appreciated:
