Centering Captions on Gallery Images

Site URL: https://www.fchc.us/

Is there a way to center the captions under images that are in a gallery block? I can't figure it out and am wondering if I need special code for it. On the website, the gallery of topic is the one on the bottom of the 'Meet the Staff' section of the website, under About Us. 

add this to your sites custom css (if you want it to happen for all galleries). 

p.gallery-caption-content { text-align:center; }

if you want to just do it on that page then wrap the same code in <style> blocks and put it either in the page header (needs business/premium plan) via the Advanced section of the page settings, or put it in a code block on the page.

<style>
p.gallery-caption-content { text-align:center; }
</style>

Thanks so much for that lightning fast response!
