I have a question regarding column count templates. I coded the following template a while back which would make row-based templates easier to create for fast overview of cast and episodes for example. I have no idea how other people see it and it is meant for viewer's ease so I'd like it to appear as such for everyone. I have looked at more attentive wikis but none of them use such a template...
 * On my (Windows 7) laptop (pic: left) it still appears as 3-4 rows
 * On my (Windows 10) PC (pic: right) it appears as one big long row.

Can someone please help me with this?
