I want to list my tags and categories (front page) in two columns; works great on web. But on mobile, it gets broken, they just get listed one after another. I tried with styling the margin on the tags column, but that was not solving it. I also tried with manually creating two columns and it did not help.
are you using the GenerateBlocks plugin ? If so use the GB Grid Block for your columns ( instead of the Columns Block ). You can the select each Grid Column, and in the Mobile Tab preview set there width to 50%, this will keep 2 columns on Mobile.
