Site origin Resposive on mobile devices

Helly everyone,

I’m using Site origin to build my own website.
Now i have a problem, i have in 1 row 3 text editors.
So i have 1 row with 3 text columns next to eachother.
When i use my website on my mobile devices, They arent next to eachother anymore.
Wordpress/siteorigin put the 3 columns under eachother.
I would like to see them next to eachother, just like my normal site.
Can someone help me change it?

Kind regards,
Tom
