Unfortunately I’m developing it on my computer. I’ll give you a link to see what it does:
initially the icons should be large and then move to medium and become small as the screen becomes smaller.
the text in the description should also change accordingly from large to small
instead the icons are initially small, then increase and then become small again.

Perfect, tnx
