hatch posts link location

I am using the hatch theme and trying to use the posts for my portfolio of projects. I would like them to run horizontally across the bottom of the page in a row, but they are running vertically down in a column. The sample theme image has them horizontal, how/ where can I change this??

Also, is there any way to not have the posts show up on my home page? Only on my “environments” page?
