Trouble with columns row and responsive

Hi,
I’m trying your nice King Composer on a website (local not online)
and I’ve trouble with columns row:

I’ve used a 3 columns row
In each column I’ve 2 items :
– single image
– raw code with some text (just 3 little lines)

On desktop screen and on mobile screen, it’s ok, but when I test on ipad or similar screen size the text goes on left side and is no more just under the pic …

Could you help ?

Thanks
