I have tried the Grid Columns plugin but… maybe the WP editor is messing with the formatting as I save the page and/or navigate through Visual/Text editors? I had a hard time trying to make a grid with 6 “blocks” (3×2) of “Font Awesome icon + description”.
Perhaps I am just not experienced enough? I would definitely pay some money for a good [video] tutorial explaining how to make better use of this plugin’s powers.
What it means is that on desktop it shows up as 3 columns per row (33%), on tablet shows 2 columns per row (50%) and on mobile shows 1 column per row (100%).
