ok, I’ll try to be more specific. The link I gave you http://www.puntomatedilizia.com has a slider on top of the page which works fine, than going down you’ll find a section called “news ed eventi” with 3 articles preview. This article slider has autorotation, so what happen is that when one of the pages of this article slider doesn’t have 3 articles showing, the size of the slider changes in mobiles creating a very bad effect. Problem is articles slider works horizontally on desktop mode, but it does it vertically in mobiles.

I hope you can see what I’m talking about this time. Thanks for the help anyway.
