Hi There,
1- You can add more padding top and bottom to your section in order to get make the height bigger.
To do that you need to click on your section on Cornerstone and add padding top and bottom, I reccomend you using % instead of px, that way it responds better on mobile.
2- You need to click on your row, and beside the row name you will find magnifying lens, click on it and deactivate Column Container.
Hope that helps
Joao
