Text Columns with image - need 4 images on 1 row - Debut theme

[FS1949]

Hello, 

I am using debut theme and I have 4 columns with images but i need them to be in one row both on my webpage and on mobile. 

My website is: 

www.thefuzzysprout.com 

This is the image of what I need to be in one row. 

Can someone assist with what the code can be?

Thank you!
