Hello
I need to center align the thumbnails on mobile. I'm using Seamless as Layout template.
I tried to add

ul.sigProSeamless {
margin: 8px auto!important;
padding: 8px 0!important;
list-style: none;
clear: both;
overflow: hidden;
text-align: center;
}
but it doesn't work.

this is an example page: www.marinellihome.com/it/collezioni/in-scena-atto-primo/fiordiloto
Thanks
