Creating a section list that works good on mobile as well as pc

Hi

I would like to know how I can achieve the following 

1st           Title of image.        By person 1

2nd        Different length title of image     By person 2

With each column starting at the same point to have a list that looks good on pc and mobile. I can get it looking great on the pc by using 3 different size text block but on mobile it shows all the first text block then the second then third and looks a mess. Is there anything I can do? This is for the winners and highly commended competition entries.
