List collection section GRID on Home Page Dawn Theme

[SJ16]

Hi

I need help with the grid on my List Colection section on my Home Page (Dawn Theme)

I tried with some code editing but still can't erase the space or margin around each image. Also I would like Titles are on image with (shop now) buttons.

This is how my section looks right now...

This is what i would like to fix and change...

This the inspection code of my section...
