Hi @charlienerdica
The code I have shared covers 4 columns, no matter how large is the main container on your site, apart from this code:
@media all and (min-width:320px) and (max-width: 782px) {
#forminator-module-11 .columns4forminator .forminator-radio-inline {width:100%;}
}
which says that labels should be displayed one by one in 1 column below 782px width.
Now there are 2 ways of making some improvements for the thing you ask.
1st one is to make static width for those labels and that will reduce each column width.
2nd one is to simply close form shortcode in a div tag with some static width. For example this one:
<div style="width:1000px;">FORMINATOR SHORTCODE HERE</div>
Of course, play around 1000px value and see which one will be the best for you.
Kind Regards,
Kris
