No Container for row leaves text extended on screen

Hi,

I would like to be able to mimic what you have done on your page here: http://theme.co/cornerstone/ where the images hug the sides of the screen without a container but the text does not extend to the end of the screen and sits within its own container. How do I achieve this?

Currently on https://parracatholic.org/cyp-home/ you will see in the formation section on the home page what I am trying to achieve. I have created a row with columns 1/3 and 2/3 which has the column container off. While I can insert an image into the 1/3 column and it hugs the LHS of the screen the RHS 2/3 column leaves the text hugging the screen too, I want it to line up with the column container above in other sections. How do I achieve this?
