on my website lenguadefuego.com is everything working quite well so far.
But visiting it from a mobile phone produces bullshit - the header (jumbotron) is somewhere, the logo (main center title) somewhere else, and the menu is white letters on white ground (its white, because the header image is black), because its not on the image, but somewhere else.
When I tap somewhere on the screen, at the right place the menu opens and I can click on the entries.
Maybe you just look at it at yourself
I would really appreciate if somebody would help me with this!
