Logo Sticky position in Menubar with iphone

Dear Developers,

my logo, positioned in logo-small, is always shown in the menubar which sticks to the top.

There should only be the navigation on top, if I´m scrolling down on my iphone. Can you help me out?

Another question: Is there a code, to hide an article on smartphone view?

If you dont want to show your logo in mobile view, disable the "logo-small" module position

And if you dont wanne show an article on mobile device you have to put a DIV around your article content, like this:

<div class="uk-hidden-small">
here comes your article text
</div>

Hallo! I wanna have to logo to be shown on mobile device but I dont want it to stick on top if i scroll down.

Sorry what?
And where should the logo go in mobile devices? It must be in sticky position...

It should act the same way as it does in desktop view. Stay on top and disappear when I scroll down. The only thing that should stay on top is the menubar. Just the same way as it is with normal view.

Sorry thats not possible with a few clicks.
I mean its possible with many template modifications and PHP/ CSS Know How.
But please take in your mind that customizing is no regular template support. Maybe you should hire a web designer.
