jQuery Masonry - Issue with Fluid layout

[JeffreyC]

I am working on a site which was made by another developer using the jQuery Masonry plugin. The site is working fine but the layout is responsive. The problem here is that I need to add some elements which are non responsive and due to this I need to make the whole site non responsive. The site contains lots of style sheets and JavaScripts, so I don't know where to start and what code to supply as reference. But it would be helpful if someone can suggest obvious ways by which I can make the layout non-responsive.So far I have removed all the @media elements from style sheets...but this hasn't worked...Thanks in advance...
