Creating space only below a cms item - Mobile

Hello !
I’ve been trying to insert a space below each image (within CMS item) - but whenever I add a bottom margin/ or a div block below the element it is also added on top of the first element, so instead of creating space for the type below the image moves down as well. ( I hope I’m making sense)

Below is a screenshot of what I am trying to do (did a non CMS version)
The lower image moves down to make space for the type.
