Window size

Hi There,
I love your enfold theme and have been building a client’s website with it.

I can’t seem to figure out how to make the theme stop responding (re-adjusting) to the window size. My client has requested for the site to not adjust once you scale the window size to 1020px or below. Similar to This Site. As you can see from this link, once the window size gets smaller than 1020px. It stops readjusting and the window just begins to cover the site. This is exactly what my client want.

This problem becomes particularly evident with the masonry gallery. I’m only using 3 images across as a sort of highlight feature on the homepage, right under the initial homepage slider, running the full width of the page. But once I scale it down it begins to readjust and at one point – just before all three stack on top of each other and looks the way it would on a mobile device – it will have two across the width of the window, stacks the third image below, and has an empty space next to the third image (hopefully that makes sense:) – all of which my client hates. Lol. But I think this issue will be resolved once the theme stops responding to the window size at a certain point.

Inversely, being that I am only using 3 images for the masonry gallery on the homepage, once you expand it on a large screen, there is space that opens up as though it wants a 4th image there. As I slowly drag my window screen wider the images adjust perfectly, but once it gets to a certain point the images get smaller and creates the 4th space. Is there away to prevent this from happening?

Please help me with resolving these issues.

Thanks Much!:)
Justin
