Strange gray line on the page

Hello,

On every page there is a short gray line after my page content. Every page on the site. I’ve looked at the code, at the css, template, but am at a loss as to how to remove it. It’s not on your demo page.

I’m linking the home page and in this case the line appears below “Michael & Hank” and it appears in all desktop browsers and on my smartphone.

Thanks!
