Seamless Responsive Photo Grid with Omega I'm trying to create a responsive full screen gallery based on quite a simple idea, but without success. Idea is to have full screen view of many pictures that are adapting to screen resolution responsively.

The idea you can see here: http://css-tricks.com/seamless-responsive-photo-grid/

I'm working on D7.20, Omega 3.x

And what I want to do is to have content type, let's say, "picture" and create a view, which is displayed in a fluid full screen layout and is shown in such a way like in a given example. 

But no success, it looks like it should be simple, but I cannot manage to understand how should I change the CSS to make it work...

It is probably possible to make similar effect using jQuery Masonry module, but I would like to do this with only CSS.
I have a kind of similar issue. I was actually trying to display different packages where the packages div's had variation in heights. I tried to align them using css without any luck. 

so I then tried Isotopes and that worked perfectly.

You should also try https://drupal.org/project/isotope it comes with Example Context Reaction for Isotope.

there is also https://drupal.org/project/views_isotope module

You can also use 

https://drupal.org/project/views_fluidgrid
https://drupal.org/project/masonry
https://drupal.org/project/masonry_views
