Menu position below fullscreen slider / minified css

Dear Seventhqueen-Team,

i have search the Forum, but i found only a post from 2014 with no content *menu below slider* (you could not respond to this topic).

For my company site i will add a new fullscreenslider (Rev-Slider or Layerslider) and the menu should be below the slider. It should appear when the user scroll down. Like the demo from themeco

Is this possible with Kleo?

You can have a look on my dev-site:

dev.mapvis.de

user: kleo

pass: *seventhqueen*!#support_laura

Then i have a second question to the minified css  and the child-theme in wordpress (i´m only a designer).

I have try to add the folder-structure to the child theme to change the background-color of the ul-products (transparent) and the <div class=”product-loop-inner“> to white. Because i have a grey background in my row and as kleo out of the box it looks bad with a non white background 😉

But wordpress did not load the files in the child-theme. At the moment i have change the files in the master-theme, how do i tell wordpress to use the files in the childtheme?

And, what is even more importand for my understanding, how do i rewrite the *.min.css-files from the *.css-files?
I can change the code in the *.css-files without any problems, but any optimizer tool (i guess) write a *.min.css-file which is used by the frontend. How should i handle that ( i know i´m a noob in this area…)

It would be nice if you could help me with my questions.

Best Regards

Markus
