My grid doesn't work on mobile


I am building an improved V2 version for my website and unfortunately I cannot make it responsive on mobile. My elements are not getting the same width based on the content, while I need it to. As an example on my screenshot, check Wizmo.

Also I can’t find a way to make “emplacement link” stay at the bottom of the div. Could you please help me?
Attached is my read-only link, and a screenshot

Thanks a lot!!
