Mobile device page

[nailstudiowebsite]

Hey guys it's me again

Now i finished the desktop version of my Homepage nail-barbara.ch
Now theres a problem with my mobile page but let me begin on the first point

First:  background repeats itself wich i think is ugly to look at i'd like to have it fixed like on my desktop.
Second: The main text, menu and the dropdown of the menu is too small and doesn't fit on the background it's to big.

As example on the page: "Preise"
Could someone look at thet template: sobresot of the page: WebsiteBaker.at and tell me how i can fix this, i got feedback of my costumers and i'd like to change this that it looks good to look at again?

Thank you for your help
