Changing the caption overlay position

Hello!

I’m trying to get the caption of the image (that was added via the insert shortcode button) to be below the image, instead of an overlay. I’ve played around with some css and can’t seem to figure it out. Is there a quick line of css you could help me out with? I’m trying to get it to be black and left aligned, but if you can help me get it below the image, I’ll figure the rest out. Here’s an example:http://justhost.insightpd.com/record-turnout-for-2014-healthtech-summit-at-insight-product-development/

This is my dev play site…

Thanks!
