Language Switch

Hey there,

I am using 7.1 and my default language is german.

I want a simple and good looking german/english switch option on the home page (i dont want a cover page etc.).

I have injected already a code that makes only the default language main navigation visible and hides the english ones - i have done that by giving each folder and page a "/de/.." or "/en/.." URL slag. The code makes the "en" ones invisible. 

Now i want a code that creates a nice looking language switch somehwere on the top on my website (header etc.).

Right now it looks like that (see attachment) and i cant even click on either on them..and the switch looks very weird and unprofessional.

Please send help! I´m a beginner in coding..:)
