Hello,
Could you please explain what is col-sm-12 col-md-5?
From documentation:
<div class=”row single-gallery-col2″>
<div class=”single-col2-text-wrap col-sm-12 col-md-5 sticky_column pull-right”>
…

Also:
I’d like to display single image and fit into the screen using 2 columns portfolio item view (project-item-2cols-gallery-left.html).
I want to avoid scrolling. This is necessary with tall images now.
How can I do it?
I guess there are 2 ways:
One is to cut image to fit one screen.
The other is to add some white space, so that complete image can stay proportional.
What would be your recommended solution?

Thanks!
Bartek
