Problems with columns on Ipad portrait.

Hi!
Sorry, I´m having problems again.

There is two problems showing when entering the first page on my site (https://www.sudersand.se).
1. I´ve added the code in quick css:
@media only screen and (max-width: 990px) {
.only_desktop { display: none !important; }}
and added only_desktop in i 1/4 column. The column seems to disappear but there is still a small “gap” showing. (see attached image)

2. On the swedish site this is ok, but when entering the english and the german sites the images “shrinks” (only on portrait.) I´ve tried to look for the problem but I have no idea why they are behaving like this. (see attached image.) Not all images – only two of them.
(And of course, problem 1 is appearing here aswell.).

Thank you!

Regards Johan
