Hello, haven't been able to figure this out. When I add padding to a markdown block it moves the last block off grid to the right. When I take the padding off its aligned with the grid.

The size and spacing of each "card" when utilizing a list section looks perfect, but I'm using markdown blocks instead now and the grid causes an issue with the size and spacing of the cards. I'm trying to figure out how to adjust the width of each block hence adding the padding but I think I'm approaching it the wrong way.  

@Power_tech thanks for the reply. I initially went with a Column Section (i believe that's the same as a "list" section) and the spacing was perfect, with 5 columns and 2 rows and a 20x20 grid gap. That's actually what I'm trying to replicate now. 

I then ditched the column section and went with markdown blocks since getting the font styles to format properly and adding the icons worked out much better with a markdown block following @tuanphan https://forum.squarespace.com/topic/162767-free-template-pricing-table/ instructions with some minor edits. 

Is there any way to achieve the same size/spacing of a column section with the markdown blocks?

I'm testing this out now and will post back with results. Appreciate the help

Thank you, that was awesome. Worked perfectly.
