Howdy,

I have this code set for a handful of pages, but only want the margins adjusted in the desktop view (so the margins are not adjusted on an iPhone etc.) Not sure the best way to do this.

Page: alchemisteating.com/products-and-services/

/* Products and Service Page Side Margins
------------------------------------------------------------ */
.page-id-2463 .entry-content {
margin-left: 125px !important;
margin-right: 125px !important;
}

Cheers,
Casper
