I seem to have a similar problem when I put a button inside a grid column. I want to align the button to the bottom because the height of the text varies depending on page width. I worked out that I can set the minimum height of the grid column so I set it to 380px. How can I align my buttons to the bottom in this generate blocks info box? Is there some css that I can add to the customizer so I can apply an additional css class to the button?
