Hi there!

Sorry for the inconvenience.

Is this presentation made with Articles addon? Can I have your site URL to check it?

Best Regards

The solution : Custom css :

@media screen and (max-width: 580px) {
.sppb-col-6, .sppb-col-3, .sppb-col-4, .sppb-col-8, .sppb-col-10 {
  -ms-flex: 0 0 100%; flex: 0 0 100%; max-width: 100%;}
.sppb-addon-articles .sppb-addon-article {padding: 0px 10px;}
}

I use the edulif model with quickstart, the solution was in the forum but I hope that the next update will remove this code
