Sorry it took me a long time to answer, but I was sick and didn’t work.
Thank you so much! it worked :)

hi
I think you didn’t understand me.
I don’t want the 3 pooter eras to be one beside the other.
I want era 1 and 2 to be beside each other and era 3 to be underneath both era 1+2.
and both rows will fill all of the width.

I was able to do it on the desktop by using the HTML widget and 1 footer era, but it didn’t work on a mobile screen.

how can I control not only the columns of the footer but also the rows?
