on PWA (desktop style) it looks like this:

for the gallery issue am using The HP 745 G4 "14-inch display". the gallery was always fine on my screen in mobile style but lately I see it like that. am also using windows 10.

Hi @Jaifroid ,

I would like to work on this issue

I can investigate the root cause and submit a fix.
Please assign this issue to me if it is still open.

Thanks!

@Abhinandankaushik This is a complicated issue to do with intricacies of the styling system, and I don't believe it's a good first issue. Please note this repository is downstream of Kiwix JS, and it is much better to look for issues in that repository rather than here.
