Everything is working perfectly fine on my end.
“Zooming in”, is not something that people do occasionally when viewing sites, so I wouldn’t worry about that since it’s not really an issue.
When you do “Zoom In” on websites, all sites have the exact same result/response. It’s definitely not something you should be concerned about, and I don’t think it would be wise to design your code around a page being zoomed in, as it will be off and inconsistent with all of the visitors who you view your site regularly. Plus most visitors to your site won’t be zooming in to view your content anyways.
Your design is looking pretty nice! You should send Wes an email or let him know about it. I think he’s building a showcase section, but I’ve also noticed he shares customer links on Twitter.
