Module above each other

Hey, I'm working on the website. You have taken a moment when only one module was integrated. Now I was able to detect a fault, which is worse... unfortunately... please take a look, logo and background, at the four sites. Do it is a jQuery loading problem? Can I stop loading in your script?

Website

I don't see any JS error ...
in my script I use only the jQuery from joomla!

Do you know if I combine Parallax with Smooth Scroll, it will no longer show up correctly?

Now it's getting clearer. Ok I think there is a solution. I could adjust it to the size again. Can I exhibit the background augmentation? and installing a second module does not work, right?

Can I exhibit the background augmentation?

hu ... what's that ? sorry but I should be tired because these words does not make anything that I can understand in my brain :S

I would like to help you, but really I have some problem to understand what you want to do. May be it is my bad

you can load multiple parallax modules in the page, this is not a problem as you can see in the demo on joomlack.fr

it's me... bad english... and bad google translater

I want no background zoom. is it possible?

and I would like to integrate a second content module within the "parallax module". for example "login module" and "smooth scroll module" within "parallax module". not only one of them. important for me is to define the position of the (first and) second module.
I had an easy idea, to load two parallax modules in the same position (logo) in the template and can integrate the second content module in with exactly position. but it doesnt works right. they display only above each other. not how you say superpose...

maybe I think false...

maybe now you understand better?

so many thanks for your support!!
