Theme: inFocus; rogue bits of code

I’m a graphic designer for a marketing agency called Gremillion and Pou, and have a problem with our website. I was updating our Work section, and somehow some bit of extra code --> sneaked onto the pages and started showing up with the images on the page, shifting everything to the left:

https://gremillionandpou.com/work/
https://gremillionandpou.com/work/seminole-casino/
https://gremillionandpou.com/work/gold-strike/

It’s appearing on every page that uses the gallery function of the theme, so I’m assuming that the extra code is somewhere in the theme coding, I’m just not sure exactly how to go about finding it.

Any insight would be very much appreciated!
