On my desktop view I want a column to the left of 2 spans with 6 image links stacked vertical. There is a paragraph the right which spans 10 spans.

On my smartphone view, I want the 6 image links to appear in 2 rows of 3 image links spanning the width of the screen. The paragraph needs to appear below the image links in the smartphone view.

I am having trouble setting this up. My image links consistently appear stacked. Any hints to fix this?
