Hello,
on the home page, there were 4 sections, the first one with four feature block addon, the second with 2 feature block addon, the third and forth with only one feature block addon.
The first section, when displayed on mobile causes the others sections to overlap. When it was not displayed, the displayed sections were correct. i created a new first section with 4 image addons, and this king of addon display correctly on mobile and do not perturb the other sections.
So to solve my problem and because it was possible to do that, i made images of the feature blocks, and put them into the new section "4 images". This section is only displayed on mobile, instead of the original one which is displayed on laptop only.
Once again, this is ok because the is no interaction with the elements of this section.
The problem comes in fact from the perturbations caused by feature blocks elements on mobile. Don't know how to solve without replacing feature block by images (when it is possible).

I solved my issue changing from feature block addon to image add on, because this was possible for my case. Hoxever it did not solved the problem as long as you need feature block addon. So the question still there. Because tomorrow, later, i could need using featureblock as feature block, i mean with for instance a button with a link, that users could press on.
