Trouble with responsive columns

[Cheddaa]

Hello, So my layout looks great when its in regular screen size but once it goes to mobile it isn't centered and has no spacing in between each picture, which is how i would like to be.  I am somewhat new to responsive design and am currently teaching myself how to use it, so anything helps at this point!  I am using the grid row with columns from the insert panel.
