Flexslider in background

[Tata]

I use the plugin on some pages. I try effortlesly get the plugin running in background of a header. I mean - changing pictures in header's background and another texts and transparent logo with animations in header's foreground. Is there any pure CSS way for it?
There are many js/jQuerry trick on the internet, but "layering" by CSS would be fine, though.
See e.g. http://zusnobela.sk and http://nobela.cmsimple.sk. I would like to combine these two banners (preferably fading backgrounds and animated foreground).

Is there any pure CSS way for it?

Here some examples:
Pure CSS3 Slider with multiple animation options + Demo
CSS slider fade in effect
CSS slider 2 fade in effect
CSS Slider with image zoom

Thanks, but I have seen these and something from one of them is used here http://nobela.cmsimple.sk. It's my fault that I have not specify that I ment the plugin Flexslider_XH (as used at http://zusnobela.sk). My question is then if this plugin can run as a banner background and the rest (floating in logo and the newsbox) would run on higher layer in the same space.
@EDIT
I also think about using a newsbox for the banner with the flexslider on its background. This would make it simple to use different bannner slider for each page.
