I would like change positioning in top-b when I see the website in a mobile device that each block can see top to bottom.


The website if you can see the question is:

How can I change this block behaviour?

Thank you very much for your attention

Hello,
please take a look at the Template options > Layout > Grid

Another option is to remove the second right module which is published on "top-a" on mobile phones.
