Photo Caption Size

I am sorry in advance as I suspect this has been addressed multiple times. I have tried some of the Quick CSS suggestions but I have not yet located anything that works in my situation.

My page (in process) is listed in Private Content below.

I need help on the (white) photo captions at the bottom of this page, under the section “Shop by Store Category. Using the lefthand photo element as an example, I would like to increase the text size on these captions. Ideally the caption fix would not be site wide, but just for these phot elements at the bottom of this page. There will be 9 total elements 3 columns x 3 rows.

If it needs to be a site wide solution I can likely work around that. —Bill B
