So I've never seen anything quite like this...This is a site that I helped layout for someone who had done a design in photoshop (not my design disclaimer).
It appears to working fine in Chrome, Firefox, Android, iPad, iPhone... but Safari in Mac shows this weird white box over the main images on the front page. I've confirmed this on two machines as well as browser test screen shots. The really weird part, is that when I open the develop console and inspect element in Safari, it immediately goes away.
I also pinned it my dashboard in mac and the screenshot thumbnail shows the site without this box as well. I really have no idea what is going on, having never seen anything quite like this, and could really use some help
