So I found a possibly crude answer to the question. I got my first clue here in Zed’s post where he mentions a responsiveness cutoff point of 1280 pixels. So I used Notepad++ to search the whole Fluida theme directory for ‘1280’ and found what I needed in fluida/resources/styles/responsive.css.
For my purposes, simply changing the ‘1280’ on lines 5 and 11 to ‘1190’ was enough. You could try fiddling around with all responsiveness width pixel values, as they are in more places that in just lines 5 and 11
For example, you could set max width for any view that isn’t desktop to 1 pixel, and set min width for desktop view to 1 pixel. This way, screen wider than 1 pixel gets desktop view with the sidebars on the sides. CAUTION: this example will almost certainly break the look of your website on mobile where the website will be nearly unreadable. I recommend rather tweaking it to your needs.
This doesn’t disable responsiveness, but was enough to meet my needs.
RESOLVED.
