Stop widgets resizing on page change

Hey everyone,

I’m using the customizr theme and using siteorigin page builder to build my site. Essentially I’m trying to stop the widgets within the row (generally two to a row) resize and drop underneath each other when the website resizes. I’ve tried adding in this code

html {
min-width: 1200px;
margin: 0 auto;
position: relative; /* Fix for absolute positioning */
}

which sets the minimum width for the site but the widgets are still re-alligning. Any idea on how to change this?
