How to get photos to stack left to right rather than in columns on mobile

Hi,

I have a destinations page for my travel blog on which I use photos as buttons to allow readers to click through to destination guides.

They are set out alphapetically with three on each line for example

Botswana Ghana Kenya
Rwanda Seychelles South Africa

They’re alphabetical left to right as this is the way people are used to reading.

The trouble is that on mobile they are then alphabetical order as thew follow the colums, which is a tad annoying. I end up with:

Botswana
Rwanda
Ghana
Seychelles
Kenya
South Africa

Is there any way to change this without having to put in a custom module that shows only on mobile?

Thanks,

Ben
