can anyone help me?

Ok
tank

I solved to set max-width how to see below:

/*Pagina checkout*/
#customer_details.col2-set .col-1 {
-ms-flex: 0 0 8.333333%;
flex: 0 0 8.333333%;
max-width: 100%;
}

#customer_details.col2-set .col-2 {
-ms-flex: 0 0 8.333333%;
flex: 0 0 8.333333%;
max-width: 100%;
}/*allargare la colonna del form per la fatturazione nel checkout*/

Sorry for my english I meant that since header-shop file doesn’t exist, template shop loads the default header. But I think you can make a copy of default header (header.php of active theme), rename it header-shop, and customize it as you like.
I hope I was able to explain myself

I think I understand header_shop does not exist and the shop starts generic header template.
thanks anyway

Ok thank
