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!

Can you share site url? We can help easier

span.Header-nav-folder {

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

This worked, as always.  Thank you, @tuanphan

You're welcome.

I have some feedback on your site, hope it useful.

1. I see header is too high on scroll, if you need to reduce logo size on scroll, I can give the code.

2. Do you want change order of some text/images on mobile?

3. Do you want: show folder items under Our Brand on Mobile menu without clicking on Our brand?

4. I think product title on mobile is big?? You can add this CSS to reduce size

/* reduce product title size mobile */
@media screen and (max-width:640px) {
h1.ProductItem-details-title {
    font-size: 30px !important;
}
}

5. (Tablet) Space between breadcrumb - header big?

If you feel same me, I will give the code to reduce space.

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